This document describes the features and characteristics of the 16-bit CAN-enabled CompactRISC microcontroller family, including high performance, integrated features, and low power consumption.

54F379 is a 4-bit register with buffered common Enable input, true and complement outputs, guaranteed 4000V minimum ESD protection, produced by National Semiconductor Corporation.

The LM2937 is a positive voltage regulator capable of supplying up to 500 mA of load current. The use of a PNP power transistor provides a low dropout voltage characteristic. With a load current of 500 mA the minimum input to output voltage differential required for the output to remain in regulation is typically 0.5V (1V guaranteed maximum over the full operating temperature range).

The CLC5957 is a monolithic 12-bit, 70MSPS analog-to-digital converter optimized for use in IF-sampled digital receivers and other applications requiring high resolution, high sampling rate, wide dynamic range, low power dissipation, and compact size. It features differential analog inputs, low jitter differential universal clock inputs, a low distortion track-and-hold with 0-300MHz input bandwidth, a band-gap voltage reference, data valid clock output, TTL compatible CMOS (3.3V or 2.5V) programmable output logic, and a proprietary 12-bit multi-stage quantizer.

The 54ACTQ32 Quiet Series Quad 2-Input OR Gate is a product of NATIONAL SEMICONDUCTOR, which contains four 2-input OR gates and utilizes NSC Quiet Series technology to guarantee quiet output switching and improved dynamic threshold performance. The Quiet Series products also feature GTO output control and undershoot corrector, as well as a split ground bus for superior ACMOS performance.

The ADC088S022 is a low-power, eight-channel CMOS 8-bit analog-to-digital converter specified for conversion through- put rates of 50 kSPS to 200 kSPS. The converter is based on a successive-approximation register architecture with an in- ternal track-and-hold circuit. It can be configured to accept up to eight input signals at inputs IN0 through IN7. The output serial data is straight binary and is compatible with several standards, such as SPI™, QSPI™, MICROW- IRE™, and many common DSP serial interfaces. The ADC088S022 may be operated with independent ana- log and digital supplies. The analog supply (VA) can range from +2.7V to +5.25V, and the digital supply (VD) can range from +2.7V to VA. Normal power consumption using a +3V or +5V supply is 0.9 mW and 5.5 mW, respectively. The power- down feature reduces the power consumption to 0.03 µW using a +3V supply and 0.15 µW using a +5V supply. The ADC088S022 is packaged in a 16-lead TSSOP pack- age. Operation over the extended industrial temperature range of −40˚C to +105˚C is guaranteed.

The LM1084 is a series of low dropout voltage positive regulators with a maximum dropout of 1.5V at 5A of load current. It has the same pin-out as National Semiconductor’s industry standard LM317. The LM1084 is available in an adjustable version, which can set the output voltage with only two external resistors. It is also available in three fixed voltages: 3.3V, 5.0V and 12.0V. The fixed versions integrate the adjust resistors. The LM1084 circuit includes a zener trimmed bandgap reference, current limiting and thermal shutdown.

DS26C31T/DS26C31M CMOS Quad TRI-STATE® Differential Line Driver is a quad differential line driver designed for digital data transmission over balanced lines, which meets all the requirements of EIA standard RS-422, while retaining the low power characteristics of CMOS.

This document introduces the basic characteristics of the LMD18400 quad high side driver, including output current, voltage, temperature and other protection measures, as well as ON/OFF control, switch status readback and other functions.

The LM48410 is a single supply, high efficiency, 2.3W/channel, filterless switching audio amplifier. It eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design. The device operates from a single 5V supply and delivers 2.3W/channel of continuous output power to a 4Ω load with less than 10% THD+N. It offers two logic selectable modulation schemes, fixed frequency mode, and an EMI suppressing spread spectrum mode. The LM48410 features high efficiency compared with conventional Class AB amplifiers. It includes National's 3D audio enhancement that improves stereo sound quality by affecting channel specialization and widening the perceived soundstage.

LM109/LM309 5-Volt Regulator

The LM6171 is a high speed unity-gain stable voltage feedback amplifier. It offers a high slew rate of 3600V/µs and a unity-gain bandwidth of 100 MHz while consuming only 2.5 mA of supply current. The LM6171 has very impressive AC and DC performance which is a great benefit for high speed signal processing and video applications. The ±15V power supplies allow for large signal swings and give greater dynamic range and signal-to-noise ratio. The LM6171 has high output current drive, low SFDR and THD, ideal for ADC/DAC systems. The LM6171 is specified for ±5V operation for portable applications. The LM6171 is built on National’s advanced VIP™ III (Vertically Integrated PNP) complementary bipolar process.

The LM1084 is a low dropout voltage regulator with a maximum dropout of 1.5V at 5A of load current. It has the same pin-out as National Semiconductor’s industry standard LM317. The LM1084 is available in an adjustable version, which can set the output voltage with only two external resistors. It is also available in three fixed voltages: 3.3V, 5.0V and 12.0V. The fixed versions intergrate the adjust resistors. The LM1084 circuit includes a zener trimmed bandgap ref- erence, current limiting and thermal shutdown. The LM1084 series is available in TO-220 and TO-263 pack- ages. Refer to the LM1085 for the 3A version, and the LM1086 for the 1.5A version.
