national semiconductor DS485 Low Power RS-485/RS-422 Multipoint Transceiver handbook
The DS485 is a low-power transceiver for RS-485 and RS-422 communication. It features low quiescent current, short-circuit current limitation, and thermal shutdown circuitry for protection. Both the driver and receiver support TRI-STATE outputs, and the receiver has a failsafe feature for high-level output when the input is open circuit.
National DS40MB200 handbook
The DS40MB200 is a dual signal conditioning 2:1 multiplexer and 1:2 fan-out buffer designed for use in backplane redundancy applications. Signal conditioning features include input equalization and programmable output pre-emphasis that enable data communication in FR4 backplanes up to 4 Gb/s. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. All output drivers have 4 selectable steps of pre-emphasis to compensate for transmission losses from long FR4 backplanes and reduce deterministic jitter. The pre-emphasis levels can be independently controlled for the line-side and switch-side drivers. The internal loopback paths from switch-side input to switch-side output enable at-speed system testing. All receiver inputs and driver outputs are internally terminated with 100Ω differential terminating resistors.

National LM75 handbook
This document describes the analysis of pesticide 1,2,3,4,5,6-C6H6Cl6 concentration in seafood samples using Agilent EnviroPrep and gel permeation chromatography (GPC). The EnviroPrep column, filled with a high-resolution macroporous packing material, was selected for separation. The column is made of stainless steel and can be used in any high-pressure liquid chromatography system. The macroporous packing material has a strong and permanent pore structure, providing excellent separation efficiency in non-sample loading-intensive analysis. The small pore size eliminates interference from high molecular weight compounds and maximizes separation efficiency.

National LM748 Operational Amplifier handbook
The LM748 is a general purpose operational amplifier with external frequency compensation. The unity-gain compensation specified makes the circuit stable for all feedback configurations, even with capacitive loads. It is possible to optimize compensation for best high frequency performance at any gain. As a comparator, the output can be clamped at any desired level to make it compatible with logic circuits.
National Semiconductor LM741 Operational Amplifier handbook
LM741 is a general purpose operational amplifier produced by National Semiconductor Corporation, which features improved performance over industry standards such as LM709. It can replace 709C, LM201, MC1439 and 748 in most applications. The amplifier offers many features that make its application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, as well as freedom from oscillations. LM741C/LM741E are identical to the LM741/LM741A except that the LM741C/LM741E have their performance guaranteed over a 0˚C to +70˚C temperature range, instead of −55˚C to +125˚C.

National LM7301 handbook
The LM7301 is a low power, 4 MHz gain-bandwidth, rail-to-rail input-output operational amplifier. It offers features such as greater than rail-to-rail input range, full rail-to-rail output swing, large capacitive load driving ability, and low distortion. With a supply current of only 0.6 mA, the LM7301 supports new portable applications without draining battery life. It can be driven by voltages that exceed both power supply rails, eliminating concerns over exceeding the common-mode voltage range. The rail-to-rail output swing capability provides maximum dynamic range at the output, which is important for low supply voltage operation. Operating on supplies of 1.8V–32V, the LM7301 is excellent for a wide range of applications in low power systems. Placing the amplifier right at the signal source reduces board size and simplifies signal routing. The LM7301 fits easily on low profile PCMCIA cards.
