CD74HC237PW

Overview

The CD74HC237PW is a high-speed CMOS logic decoder and demultiplexer manufactured by Texas Instruments. It features a 1x 3-to-8 line configuration with address latches, housed in a 16-pin TSSOP surface-mount package. The device operates on a single power supply ranging from 2V to 6V and supports an extended industrial temperature range of -55°C to +125°C. It provides non-inverting outputs with a maximum output current of 5.2mA for both high and low states.

Feature Summary

• Integrates address latches for stable decoding operations
• Includes three enable inputs for flexible system control
• Delivers balanced push-pull outputs for reliable signal driving

Applications

• Address decoding in microprocessor systems
• Data routing and distribution networks
• Memory chip select generation

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm that the operating voltage and temperature ranges align with your design constraints before finalizing procurement.

Selection Notes

Select this component when a 3-to-8 decoder with integrated address latching is required. The HC series offers compatibility with standard CMOS logic levels. Consider the TSSOP package dimensions for PCB layout constraints and verify thermal performance within the specified operating temperature limits.

Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. It serves as a specialized variant within the decoder and multiplexer category, distinguished by its internal latching capability which simplifies interface design for sequential addressing applications compared to standard decoders.

Replacement Considerations

Compatible substitutes include the CD74HC237M96 (SOIC package) and the CD74HC237PWR (Tape & Reel packaging). Verify pinout compatibility and electrical characteristics before substitution.
