54ALS374J/883

Overview

The SN54ALS374J/883 is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments, formerly National Semiconductor. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 20-lead ceramic dual in-line package (CDIP) suitable for through-hole mounting. It supports a wide operating temperature range from -55°C to +125°C and includes TTL-compatible inputs.

Feature Summary

Octal D-type edge-triggered flip-flop architecture with three-state outputs
TTL-compatible input logic levels
High radiation hardness and single-event upset immunity
Hermetic ceramic packaging for harsh environments

Applications

Aerospace and satellite data bus interfacing
Military-grade digital storage systems
Harsh environment control logic circuits
Radiation-hardened sequential circuit designs

Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments acquired National Semiconductor's logic business. Confirm that the specific suffix /883 indicates compliance with MIL-STD-883 standards for hermeticity and reliability. Ensure the component matches the required radiation hardness specifications for the intended application environment.

Selection Notes

Select this component when radiation tolerance and high-temperature operation are critical requirements. The ALS series offers a balance of speed and power consumption suitable for complex military logic applications. Verify pinout compatibility if replacing older National Semiconductor parts with current TI equivalents.

Part Context

This part belongs to the 54ALS374 family of octal flip-flops. The /883 suffix denotes qualification under MIL-STD-883, ensuring hermetic sealing and enhanced reliability for defense and space applications. It is functionally similar to other 54-series logic devices but optimized for radiation resistance.
