SN74AS20DB

Overview

The SN74AS20DB is a dual 4-input positive-NAND gate from the Texas Instruments SN74AS series. It operates on a single supply voltage (VCC) ranging from 4.5 V to 5.5 V, with a nominal value of 5 V. The device features push-pull outputs capable of sourcing up to -2 mA and sinking up to 20 mA. Switching characteristics include a maximum propagation delay of 5 ns at VCC = 5.5 V. It is rated for operation within an ambient temperature range of 0°C to 70°C.

Feature Summary

Contains two independent 4-input NAND gates performing Boolean logic functions in positive logic.
Features high-speed switching performance with low propagation delays characteristic of the AS logic family.
Provides robust output drive capabilities suitable for direct interfacing with standard TTL loads.

Applications

General-purpose digital logic circuit design
Boolean function implementation in microprocessor systems
Signal gating and data routing applications

Procurement Notes

Verify that the specific ordering suffix 'DB' corresponds to the SOIC-14 package variant as documented in the official datasheet. Confirm RoHS compliance status and lead finish specifications against the latest Package Option Addendum prior to procurement. Ensure the component meets the required operating temperature range for your specific application environment.

Selection Notes

Select this component when high-speed NAND logic is required within the AS family. Compare power consumption and speed against ALS variants if lower current draw is prioritized over switching speed. Verify pin compatibility and package dimensions against existing board layouts before finalizing the selection.

Part Context

This device belongs to the Texas Instruments SN74AS (Advanced Schottky) logic family, known for superior speed compared to standard 74LS devices. It shares functional compatibility with other 74-series logic families while offering faster transition times. The part is designed for use in commercial-grade electronic equipment requiring reliable digital processing.
