SN74HCS137DR

Overview

The SN74HCS137DR is an automotive-grade 3-to-8 line decoder and demultiplexer from Texas Instruments, belonging to the HCS logic series. It features three address inputs and eight outputs, housed in a 16-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation. It functions reliably across an extended temperature range from -40°C to +125°C, with a typical propagation delay of 51 ns.

Feature Summary

• Automotive qualification for reliable operation in vehicle environments
• High-speed CMOS technology enabling low power consumption
• Wide operating voltage range supporting diverse system requirements

Applications

• Automotive display control systems
• Instrument cluster decoding
• Body control module address selection

Procurement Notes

Verify the Q1 suffix indicates automotive qualification status. Confirm the DR suffix corresponds to the SOIC-16 package type. Ensure the component meets specific AEC-Q100 standards required for your application. Check for any recent product change notifications affecting specifications or manufacturing location.

Selection Notes

Select this component when automotive reliability and wide voltage operation are required. Compare propagation delays against other HCS decoders if timing constraints are critical. Consider pin compatibility with existing designs using similar decoder families. Evaluate thermal performance within the specified operating temperature range.

Part Context

This part belongs to the SN74HCS137 family of high-speed CMOS decoders. It shares functional similarities with non-automotive variants but includes enhanced durability features. The HCS series offers improved speed and lower power compared to legacy HC logic families while maintaining pin compatibility.

Replacement Considerations

SN74HCS137QPWRQ1 is a verified alternative offering TSSOP-16 packaging with identical logical functionality.
