5962-9055301EA

Overview

The Texas Instruments 5962-9055301EA is a military-grade high-speed CMOS logic component, specifically the CD54HC40103. It functions as an 8-stage synchronous down counter with a binary output format. The device operates within a supply voltage range of 2.5V to 5V and supports 3.3V logic levels. It is housed in a 16-pin Ceramic Dual In-Line Package (CDIP) designed for through-hole mounting. The component is rated for extended industrial temperature ranges, functioning reliably from -55°C to +125°C.

Feature Summary

• High-speed CMOS technology ensures rapid switching performance suitable for demanding digital applications.
• Synchronous down-counting architecture provides precise binary sequence control with eight distinct stages.
• Military-grade construction utilizes ceramic packaging to withstand harsh environmental conditions and thermal stress.

Applications

• Digital frequency division circuits requiring stable binary outputs
• Timing and sequencing logic in aerospace or defense systems
• Industrial control interfaces operating under extreme temperature variations

Procurement Notes

Verify that the specific suffix EA corresponds to the required ceramic package and military qualification level. Confirm RoHS compliance status as indicated by manufacturer documentation, noting that military variants may differ from commercial standards. Ensure the ordering information matches the exact pinout and electrical specifications defined in the official datasheet before finalizing procurement.

Selection Notes

Select this component when high-speed binary counting is required in environments exceeding standard commercial temperature limits. The CDIP package is appropriate for applications necessitating robust mechanical stability and thermal dissipation. Verify compatibility with 2.5V, 3.3V, and 5V logic families to ensure proper signal interfacing within the target system design.

Part Context

This part belongs to the CD54HC series of high-speed CMOS logic devices manufactured by Texas Instruments. The 5962 prefix indicates it is a direct-read military-grade version of the commercial CD54HC40103. It falls under the broader category of counters and dividers, serving as a fundamental building block for sequential logic operations in complex digital integrated circuit designs.

Replacement Considerations

The commercial equivalent is the CD54HC40103. Verify that any substitute meets the same military temperature ratings (-55°C to +125°C) and ceramic package requirements. Ensure the replacement maintains identical synchronous down-counter functionality and binary output characteristics.
