SN74HCS137QPWRQ1

Overview

The SN74HCS137QPWRQ1 is an automotive-grade 3-to-8 line decoder and demultiplexer from Texas Instruments, belonging to the HCS logic series. It features three input lines and eight output lines housed in a TSSOP-16 package. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation. It exhibits a propagation delay of 17 ns and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust performance in vehicle environments.
• High-speed CMOS technology enables efficient decoding and demultiplexing operations with low power consumption.
• Wide operating voltage range supports flexible integration into various automotive electronic systems.

Applications

• Automotive display control systems
• Instrument cluster signal routing
• Body control module address decoding

Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-16 package type and automotive grade designation. Ensure compatibility with your PCB footprint and reflow soldering profile requirements. Confirm that the component meets all relevant automotive reliability standards required for your specific application environment before finalizing procurement.

Selection Notes

Select this component when an automotive-rated 3-to-8 decoder is required with a TSSOP-16 form factor. Compare against the SN74HCS137QDRQ1 if an SOIC-16 package is preferred instead. Consider the 17 ns propagation delay relative to system timing constraints. Verify that the 2 V to 6 V supply range aligns with your circuit design specifications.

Part Context

This part belongs to the SN74HCS137-Q1 family of automotive logic devices. It serves as a specialized decoder/demultiplexer variant within Texas Instruments' high-speed CMOS portfolio. The Q1 suffix indicates automotive qualification, distinguishing it from standard commercial variants while maintaining functional compatibility with the broader HCS logic family architecture.

Replacement Considerations

SN74HCS137QDRQ1 offers identical logical functionality but utilizes an SOIC-16 package instead of TSSOP-16. Verify pinout compatibility and thermal characteristics when substituting between these package types. No other direct pin-compatible replacements are documented in the provided data.
