CD74HC237PWR

Overview

The CD74HC237PWR is a high-speed CMOS logic decoder and demultiplexer manufactured by Texas Instruments. It features a single 3-to-8 line decoding circuit 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 operating temperature range of -55°C to +125°C. It provides push-pull outputs capable of sourcing and sinking up to 5.2mA, ensuring balanced performance across the voltage range.

Feature Summary

• Integrates address latches for stable decoding operations
• Features three enable inputs for flexible control
• Provides non-inverting output polarity

Applications

• Address decoding in memory systems
• Data routing in digital communication interfaces
• Control signal generation in embedded systems

Procurement Notes

Verify the specific suffix PWR confirms the TSSOP-16 package and tape-and-reel orientation. Confirm RoHS compliance status matches current regulatory requirements. Ensure the ordering part number aligns with the required moisture sensitivity level and reel quantity specifications for automated assembly processes.

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 wide operating temperature range for industrial environments. Verify that the 16-pin TSSOP footprint fits the target PCB layout constraints.

Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. It is functionally related to the CD74HC237M96 variant, which utilizes a SOIC-16 package instead of TSSOP. Both variants share identical electrical characteristics and logical functionality within the same product line.

Replacement Considerations

The CD74HC237M96 serves as a pin-compatible alternative offering the same logical function in a SOIC-16 package. Verify mechanical fitment differences between TSSOP and SOIC footprints before substitution.
