5962-9764201Q2A

Overview

The Texas Instruments 5962-9764201Q2A is a quadruple 2-line to 1-line data selector/multiplexer belonging to the SN54AHC157 series. It operates within a supply voltage range of 2 V to 5.5 V and features propagation delays between 7.5 ns and 11.5 ns. The component draws an operating current of 0.04 mA and supports military-grade temperatures from -55°C to 125°C. It is available in CDIP, CFP, and LCCC packages.

Feature Summary

• Provides four independent 2-to-1 multiplexing channels for signal routing
• Compatible with standard CMOS logic levels across wide voltage ranges
• Engineered for high-speed data selection with low power consumption

Applications

• Military avionics signal switching systems
• Industrial control data path selection
• High-reliability communication equipment multiplexing

Procurement Notes

Verify the specific package variant (CDIP, CFP, or LCCC) required for your assembly process, as the base part number covers multiple physical forms. Confirm that the 2V to 5.5V operating range aligns with your system power rails. Ensure environmental specifications meet the -55°C to 125°C requirement for your deployment conditions before finalizing procurement.

Selection Notes

Select this component when designing systems requiring multiple independent data paths with strict timing constraints. The AHC family offers improved speed over standard HC logic while maintaining CMOS compatibility. Consider the available package options to match your board space and mounting requirements, ensuring the selected variant meets the necessary thermal and electrical performance standards.

Part Context

This part belongs to the SN54-series, which denotes military-grade reliability and extended temperature operation. It is functionally equivalent to the commercial SN54AHC157 but manufactured to stricter quality controls. The device serves as a core building block for digital signal routing in harsh environments where standard commercial components would fail.

Replacement Considerations

Direct substitutes include other SN54AHC157 variants from Texas Instruments or compatible parts from manufacturers like ON Semiconductor and NXP, provided they match the specific package type and military qualification standards.
