SN54HC393J

Counter Dividers Overview

The SN54HC393J is a military-grade dual 4-bit binary counter from Texas Instruments, housed in a 14-pin ceramic dual in-line package (CDIP). It integrates two independent counters within a single device. The component operates on a supply voltage ranging from 2V to 6V and supports an operating temperature range of -55°C to +125°C. Each counter includes dedicated clock and direct clear inputs with parallel outputs for system timing signals.

Counter Dividers Feature Summary

• Dual 4-bit binary counters integrated into a single package
• Military-grade reliability with extended temperature tolerance
• Direct clear functionality for each individual counter stage

Counter Dividers Applications

• Military defense systems requiring high reliability
• Aerospace avionics timing circuits
• Spacecraft electronic subsystems

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'J' corresponds to the CDIP package configuration. Confirm that the military grade designation aligns with project requirements. Ensure compatibility with existing board layouts designed for 14-pin ceramic packages. Validate thermal management strategies for the specified operating environment.

Counter Dividers Selection Notes

Select this component when military-grade performance and wide temperature operation are mandatory. The SN54HC393J provides a compact solution for applications needing two separate counting channels. Consider the ceramic packaging for harsh environmental conditions compared to plastic alternatives.

Counter Dividers Part Context

This part belongs to the SNx4HC393 family of dual 4-bit binary counters. The 'SN54' prefix indicates a military-qualified version, while the 'HC' denotes High-speed CMOS technology. The 'J' suffix specifically identifies the 14-pin ceramic dual in-line package variant.
