CD74HC237M

Overview

The CD74HC237M is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 3-to-8 line decoder and demultiplexer. It features address latches for input storage and includes three enable inputs to control operation. The component operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 16-pin SOIC package. Designed for robust performance, it maintains functionality across an extended industrial temperature range from -55 °C to +125 °C.

Feature Summary

• Integrates address latches to store input data independently of the decoding process
• Provides three distinct enable inputs for flexible system control and power management
• Delivers non-inverting output polarity for direct signal interfacing

Applications

• Address decoding in memory systems
• Data routing in digital communication circuits
• Control logic in industrial automation equipment

Procurement Notes

Verify the specific suffix 'M' corresponds to the SOIC package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the required pin count and thermal specifications for your design constraints.

Selection Notes

Select this component when a single decoder with integrated address latching is required. The HC series offers balanced speed and power consumption suitable for general-purpose logic applications. Verify that the 2 V to 6 V operating range aligns with your system's power supply rails before finalizing the design.

Part Context

This device belongs to the Texas Instruments 74HC logic family, known for high-speed CMOS technology. It serves as a specialized decoder within the broader category of encoders, decoders, multiplexers, and demultiplexers. The part is designed to replace older logic families while maintaining compatibility with standard digital interfaces.

Replacement Considerations

The CD74HC237M96 is a documented alternative variant from Texas Instruments offering similar functional characteristics.
