SNJ54LS280W

Overview

The SNJ54LS280W is a military-grade, 9-bit odd/even parity generator and checker from the Texas Instruments LS series. It operates within a supply voltage range of 4.5 V to 5.5 V with a nominal rating of 5 V. The device features a propagation delay of 38 ns and draws a maximum supply current of 16 mA. It is housed in a 14-pin ceramic flatpack (CFP) package designed for high-reliability applications.

Feature Summary

• Performs simultaneous odd and even parity generation or checking on nine data inputs
• Provides complementary true and inverted outputs for flexible logic integration
• Hermetically sealed ceramic construction ensures reliability in extreme environments

Applications

• Military communication systems requiring robust error detection
• Defense avionics data bus monitoring
• High-reliability industrial control logic verification

Procurement Notes

Verify that the specific orderable part number matches the required military qualification standards. Confirm the package style corresponds to the intended board layout constraints. Ensure environmental specifications align with the operational temperature requirements of the target system design.

Selection Notes

Select this component when military-grade radiation hardness and thermal stability are mandatory. The LS series offers standard speed suitable for general-purpose digital logic. Verify compatibility with existing 5 V logic families before implementation.

Part Context

This device belongs to the SN54LS280 family of parity generators. It serves as a specialized logic circuit for data integrity verification. The military variant distinguishes itself through enhanced manufacturing controls and hermetic sealing compared to commercial equivalents.
