Counter Dividers Overview

The SNJ54HC4040J is a military-grade, 12-stage asynchronous binary counter from Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -55°C to 125°C. The device features TTL-compatible inputs, low power consumption with a maximum ICC of 80 µA, and outputs capable of driving up to 10 LSTTL loads. It utilizes a 16-pin Ceramic Dual In-Line Package (CDIP).

Counter Dividers Feature Summary

• Military-grade reliability certified for defense applications.
• Asynchronous counting with all stage outputs available externally.
• TTL-compatible CMOS input structure.

Counter Dividers Applications

• Time-delay circuits
• Counter controls
• Frequency-dividing circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'J' corresponds to the CDIP package and military qualification status. Confirm RoHS exemption requirements as military parts may not be compliant. Ensure the supplier provides traceability documentation consistent with QML certification standards for defense procurement.

Counter Dividers Selection Notes

Select this component when military environmental specifications are mandatory. The wide temperature range and robust packaging suit harsh environments. Verify that the asynchronous nature meets timing requirements compared to synchronous alternatives.

Counter Dividers Part Context

This part belongs to the SNx4HC4040 family of 12-bit asynchronous binary counters. It shares functional characteristics with commercial variants but differs in manufacturing processes and testing protocols to meet military standards. The 'SNJ' prefix identifies the ceramic dual in-line package variant.
