CD74HC237NSR

Overview

The CD74HC237NSR 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 2 V to 6 V and supports a wide operating temperature range from -55°C to +125°C. The component is housed in a 16-pin SOIC surface-mount package.

Feature Summary

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

Applications

• Data routing systems
• Memory address decoding
• Digital signal processing interfaces

Procurement Notes

Verify the specific suffix 'NSR' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with standard SOIC-16 footprint requirements during procurement planning.

Selection Notes

Select this component when design requirements necessitate a decoder with integrated address latching capabilities. The HC series offers performance comparable to low-power Schottky TTL while maintaining lower power consumption, suitable for general-purpose digital logic applications.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It is functionally related to other decoders like the CD74HC137 but includes additional latch functionality. The NSR suffix indicates a specific reel-based packaging variant distributed by Texas Instruments.

Replacement Considerations

Cross-reference with CD74HC237PWR or CD74HC237PWRE4 for alternative packaging options such as TSSOP. Verify pinout compatibility before substituting with generic 74HC237 equivalents.
