||5041 - DUAL SPST ANALOG SWITCH with CMOS and TTL versatility
by Rochester - 2013-08-10 11:17 - 31,943 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 - 6,500 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

||ROCHESTER3 - Rochester Electronics’ Extension-of-Life® Solutions: Not Just Replacement Parts
by Rochester - 2013-08-12 14:25 - 5,933 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 - 6,891 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 - 7,369 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 - 6,853 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 - 7,064 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 - 6,809 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
