5962-9758301Q2A

Overview

The Texas Instruments 5962-9758301Q2A is a dual 1-of-4 data selector/multiplexer belonging to the SN54F153 series. It operates within an extended temperature range of -55°C to 125°C and is housed in a 20-pin LCCC (FK) package. This component provides two independent multiplexing channels, each capable of selecting one of four data inputs based on address lines. Designed for high-reliability applications, it supports military-grade environmental standards while maintaining standard logic functionality for signal routing in complex digital systems.

Feature Summary

• Dual independent 1-of-4 multiplexing channels for parallel signal selection
• Extended industrial and military temperature operation from -55°C to 125°C
• Hermetic 20-pin LCCC package construction for harsh environment reliability

Applications

• Military avionics signal routing
• Spacecraft data handling systems
• High-reliability industrial control interfaces

Procurement Notes

Verify the specific suffix Q2A confirms the required qualification level and package variant. Ensure compatibility with existing board layouts for the 20-pin LCCC footprint. Confirm that the -55°C to 125°C operating range meets the thermal requirements of the target deployment environment before finalizing procurement.

Selection Notes

Select this component when dual-channel multiplexing is required in environments exceeding standard commercial temperature limits. The LCCC package offers superior sealing compared to plastic packages, making it suitable for radiation or humidity-sensitive applications. Verify that the F-series speed characteristics align with the system clock requirements.

Part Context

This part is a military-grade version of the SN54F153 dual multiplexer. It falls under the broader category of TTL-compatible logic devices designed for robust performance. The 5962 prefix indicates a direct buy or military lot traceability, distinguishing it from commercial SN54 variants.

Replacement Considerations

Direct substitutes include other SN54F153 variants with compatible pinouts and electrical specifications. Verify that any replacement maintains the same LCCC package dimensions and hermetic seal requirements for the specific application.
