CD74HC237MT

Overview

The CD74HC237MT is a high-speed CMOS logic decoder/demultiplexer manufactured by Texas Instruments. It features a 16-pin TSSOP surface-mount package and operates within a supply voltage range of 2V to 6V. The device functions as a 3-to-8 line decoder with address latches, utilizing three binary selection inputs (A0, A1, A2) that can be latched via an active-high latch enable signal. It includes two output enable inputs to facilitate cascading and demultiplexing operations.

Feature Summary

• Integrates address latching capability to isolate selection input changes from outputs
• Supports both decoding and demultiplexing configurations through dedicated output enable pins
• Delivers high-speed performance comparable to low-power Schottky TTL while maintaining low power consumption

Applications

• Memory address decoding in digital systems
• Data routing and distribution networks
• Cascaded logic circuit expansion

Procurement Notes

Verify the specific suffix 'MT' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering information with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a 3-to-8 decoder with integrated address latching is required. It is suitable for applications needing high-speed switching with low power dissipation. Consider the TSSOP package constraints and operating temperature range (-55°C to +125°C) during design integration. Verify compatibility with system voltage levels between 2V and 6V.

Part Context

This part belongs to the CD74HC series of high-speed CMOS logic devices. It shares functional similarities with the CD74HC137 but provides active-high outputs instead of active-low. The device is designed for general-purpose digital logic applications requiring reliable decoding and data routing capabilities within standard industrial temperature ranges.
