SN74AS823ANT

Flip Flops Overview

The SN74AS823ANT is a single-element, 9-bit D-type flip-flop from the Texas Instruments 74AS series. It features positive-edge triggering and a master reset function. The device provides non-inverting, three-state outputs with high drive capabilities of 24mA (high) and 48mA (low). It operates on a 4.5V to 5.5V supply, exhibits a maximum propagation delay of 13ns at 5V with 50pF load, and draws 80mA static current. Packaged in a 24-PDIP through-hole format, it supports an operating temperature range of 0°C to 70°C.

Flip Flops Procurement Notes

This component is officially designated as obsolete by the manufacturer. Availability is restricted to third-party distributors holding existing stock or surplus inventory. Verify authenticity and lot dates carefully when sourcing from secondary markets. Ensure the specific suffix matches the required package and temperature grade, as substitutions may vary in physical dimensions or electrical characteristics.

Flip Flops Selection Notes

Select this part for applications requiring high-speed 9-bit parallel storage within the standard 5V logic family. The AS series offers faster performance than standard TTL but consumes more power. Consider the 24-pin DIP package constraints for PCB layout. Evaluate the 80mA static current draw against system power budgets. Verify that the positive-edge trigger aligns with the system clock polarity requirements.

Flip Flops Part Context

Part of the Texas Instruments 74AS (Advanced Schottky) logic family, known for speed optimization. The SN74AS823 specifically addresses multi-bit storage needs where bus tri-stating is required. It complements other AS-series buffers and gates in complex digital systems designed for high-frequency operation during the late 1980s and 1990s era of microprocessor development.
