CD74HCT137MT

Overview

The CD74HCT137MT is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 3-to-8-line decoder/demultiplexer with address latches. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to +125°C. The component features balanced propagation delay and transition times, offering significant power reduction compared to LSTTL technologies. It is housed in a 16-pin SOIC package.

Feature Summary

• Integrates address latching capabilities for stable decoding operations
• Provides high-speed CMOS performance with balanced signal transitions
• Delivers substantial power efficiency improvements over legacy LSTTL standards

Applications

• Address decoding in memory systems
• Data demultiplexing circuits
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix MT against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure compatibility with 5V logic levels, as HCT series inputs are TTL-compatible. Confirm end-of-life status or obsolescence notices through manufacturer channels before finalizing procurement plans.

Selection Notes

Select this component when design requirements necessitate a decoder with integrated address latching rather than standard decoders. The HCT series ensures direct interface with TTL-driven systems without level shifting. Verify that the 16-pin SOIC footprint aligns with existing PCB layout constraints and thermal management strategies.

Part Context

This part belongs to the CD74HC/HCT family of high-speed CMOS logic devices. It serves as a specialized variant within the decoder/demultiplexer category, distinguished by its internal latch mechanism. The family is characterized by wide supply voltage flexibility and robust noise immunity suitable for demanding electronic environments.
