SN74AS1000AD

Overview

The SN74AS1000AD is a catalog logic device containing four independent 2-input positive-NAND buffers/drivers. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from 0°C to 70°C. The component features high capacitive-drive capability with low-level output current up to 48 mA and high-level output current up to -48 mA. Propagation delay times are specified between 1 ns and 5 ns under standard load conditions.

Feature Summary

Contains four independent 2-input positive-NAND buffer/driver circuits
Provides high capacitive-drive capability for demanding loads
Supports plastic small-outline (D) package options

Applications

General-purpose digital logic buffering
Positive-NAND gate implementations in industrial equipment
Driver applications requiring high capacitive-load handling

Procurement Notes

Verify the specific ordering suffix against the manufacturer's Package Option Addendum, as the 'AD' designation indicates a SOIC package that may have distinct lifecycle status compared to other variants. Confirm RoHS compliance and lead finish specifications directly with the supplier or official documentation before procurement to ensure alignment with assembly requirements.

Selection Notes

Select this component when four independent NAND gates with high drive strength are required in a surface-mount format. Ensure the application environment remains within the 0°C to 70°C operating temperature range. Verify that the 4.5 V to 5.5 V supply voltage aligns with the system power architecture and that the propagation delay characteristics meet the timing constraints of the target circuit design.

Part Context

This part belongs to the Texas Instruments 74AS series of advanced Schottky logic devices. The 74AS family is characterized by high speed and high drive capability compared to standard TTL. The SN74AS1000A variant specifically provides quad 2-input NAND functionality, serving as a driver version within the broader logic gate portfolio designed for robust digital signal processing.
