SN54LS393J

Counter Dividers Overview

The SN54LS393J is a military-grade dual 4-bit decade and binary counter manufactured by Texas Instruments. It operates within a temperature range of -55°C to 125°C and utilizes a 14-pin ceramic dual in-line package (CDIP). The device contains two independent counters, each capable of functioning as either a 4-bit binary counter or a decade counter. It features asynchronous reset inputs for both counters.

Counter Dividers Feature Summary

• Dual independent 4-bit counting sections
• Configurable as decade or binary counters
• Asynchronous reset functionality

Counter Dividers Applications

• Military defense systems
• Aerospace instrumentation
• Harsh environment control circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the latest TI Package Option Addendum to confirm active production status and exact pin count. Ensure the CDIP package variant matches the required thermal and mechanical specifications for the target application environment.

Counter Dividers Selection Notes

Select this component when extended temperature operation and high reliability are required. The SN54 series designation indicates qualification for military standards, distinguishing it from commercial SN74 variants which have narrower operating ranges.

Counter Dividers Part Context

This part belongs to the SN54LS39x family of logic integrated circuits. It shares functional similarities with the SN54LS390 but provides distinct binary counting capabilities alongside decade modes. The LS series denotes low-power Schottky technology.
