5041 - DUAL SPST ANALOG SWITCH with CMOS and TTL versatility
by Rochester - 2013-08-10 11:17 - 32,622 views
Originally offered by Harris Semiconductor and then later by Intersil before being discontinued, the 5041 is a CMOS analog switch that offers low resistance switching performance for analog voltages up to the supply rails and for signal currents up to 80mA. “ON” resistance is low and stays reasonably constant over the full range of operating signal voltage and current. The 5041 provides break-before-make switching and is TTL and CMOS compatible for maximum application versatility. The 5041 is a fully qualified military device.

The Am7838 (and Am8838) are quad high-speed
drivers/receivers designed for use in bus organized
data transmission systems interconnected
by terminated 120Ω impedance lines. The external
termination is intended to be a 180Ω resistor
from the bus to the +5V logic supply together

ROCHESTER5 - Counterfeit and Substandard Semiconductors: The Solution to the Threats
by Rochester - 2013-08-12 14:25 - 6,668 views
Counterfeit semiconductors are entering the worldwide supply chain in unprecedented numbers, and those numbers are increasing at an exponential rate. Also entering the world supply chain are substandard components that were originally viable but have been damaged through improper handling, storage, and shipping methods employed by unauthorized distributors. All of these components are causing production and maintenance failures that range all the way from inconvenient to deadly. Added to the already overwhelming mix of components that just don’t perform properly – or at all – are components armed with malicious “extras” that can destroy systems, cause malfunctions, or covertly gather proprietary information. Counterfeit and substandard semiconductors are causing loss of revenue and loss of company credibility in virtually every industry. Malicious insertion threatens national security.
ROCHESTER4 - Counterfeit Electronic Components in the U.S. Supply Chain
by Rochester - 2013-08-12 14:25 - 7,453 views
This report summary has been prepared by Rochester Electronics, LLC, an authorized distributor of semiconductors. Rochester offers a complete Extension-of-LifeTM solution: manufacture, supply, distribution, replication and re-creation, testing and certification, procurement and storage. We extend life. And, every Rochester product and service is 100% guaranteed.
ROCHESTER3 - Rochester Electronics’ Extension-of-Life® Solutions: Not Just Replacement Parts
by Rochester - 2013-08-12 14:25 - 6,103 views
Semiconductor end-of-life is an ever-present problem in every electronics manufacturing industry today, and it’s not going away. The goal has always been to purchase a replacement that is the exact form, fit, and function as the original. Lately, companies have been offering a variety to aftermarket “substitute” solutions they claim to be form, fit, and function replacements; however, manufacturers are finding from experience that these parts often fall far short of that promise.
ROCHESTER2 - The Cost of Counterfeit Semiconductors to the Electronics Industry
by Rochester - 2013-08-12 14:24 - 7,040 views
Semiconductors provide “smart functionality” to all electronic systems. These devices are key to every segment of the electronics manufacturing industry, which today exists across the globe. The high demand worldwide for semiconductors has made the market attractive to counterfeiters. Statistically, it has been proven over the years that counterfeit devices have a substantially high failure rate. Any semiconductor failure is costly, but in any of the many life-critical applications, failure can be catastrophic.
ROCHESTER1 - RoHS Compliancy in the Medical Equipment Supply Chain by 2014
by Rochester - 2013-08-12 14:24 - 7,538 views
The Restriction of Hazardous Substances (RoHS) directive has been an ongoing initiative in many industries across the electronics’ supply chain since the concept surfaced in the European Union in 2006. The EU’s 2006 RoHS directive banned the use of six substances—lead (Pb), mercury (Hg), hexavalent chromium (Cr (VI)), cadmium (Cd), polybrominated biphenyl flame retardants (PBB), and polybrominated biphenyl ether flame retardants (PBDE)—in eight categories of electrical/electronic equipment.
X28HC256DM-12 - LOW POWER CMOS EEPROM with hi-speed page write capability
by Rochester - 2013-08-12 14:17 - 7,021 views
The X28HC256 is a second generation high performance CMOS 32k x 8 EEPROM. It is fabricated with Intersil’s proprietary, textured poly floating gate technology, providing a highly reliable 5V only nonvolatile memory. The X28HC256 supports a 128-byte page write operation, effectively providing a 24μs/byte write cycle, and enabling the entire memory to be typically rewritten in less than 0.8 seconds. The X28HC256 also features DATA Polling and Toggle Bit Polling, two methods of providing early end of write detection.
UA733M - TWO-STAGE VIDEO AMPLIFIER reintroducing the μA733M version
by Rochester - 2013-08-12 14:16 - 7,228 views
The μA733 is a monolithic two-stage video amplifier with differential inputs and differential outputs. Internal series-shunt feedback provides wide bandwidth, low phase distortion, and excellent gain stability. Emitter-follower outputs enable the device to drive capacitive loads, and all stages are current-source biased to obtain high common-mode and supplyvoltage rejection ratios. The μA733C is characterized for operation from 0°C to 70°C; the μA733M is characterized for operation over the full military temperature of -55°C to 125°C.
TP82C54-2 - PROGRAMMABLE INTERVAL TIMER with advanced CHMOS III technology
by Rochester - 2013-08-12 14:16 - 6,961 views
The Intel 82C54 is a high-performance, CHMOS version of the industry standard 8254 counter/timer which is designed to solve the timing control problems common in microcomputer system design. It provides three independent 16-bit counters, each capable of handling clock inputs up to 10 MHz. All modes are software programmable. The 82C54 is pin compatible with the HMOS 8254, and is a superset of the 8253. Six programmable timer modes allow the 82C54 to be used as an event counter, elapsed time indicator, programmable one-shot, and in many other applications
