CD74HC238M96E4

Overview

The CD74HC238M96E4 is a high-speed CMOS logic device functioning as a 3-to-8 line decoder or demultiplexer. Manufactured by Texas Instruments, it operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to +125°C. The component utilizes a 16-pin SOIC surface-mount package. It features three address inputs and eight active-low outputs, along with two active-low and one active-high enable inputs for flexible control.

Feature Summary

• Provides decoding and demultiplexing capabilities using standard 3-bit binary addressing.
• Features mixed-enable logic with two active-low and one active-high control inputs.
• Supports wide industrial temperature operation suitable for harsh environments.
• Delivers high-speed performance typical of the HC CMOS logic family.

Applications

• Address decoding in microprocessor-based systems
• Data routing in digital communication circuits
• Memory chip select generation

Procurement Notes

Verify the specific suffix 'E4' confirms lead-free and RoHS compliance status against current manufacturer documentation. Confirm the 'M96' designation indicates the correct tape-and-reel packaging configuration required for automated assembly processes. Ensure the datasheet version matches the production lot to validate any recent design changes or pinout adjustments.

Selection Notes

Select this component when a 3-to-8 decoding function is required with mixed polarity enable controls. The HC series offers compatibility with standard TTL logic levels while maintaining low power consumption. Consider the wide temperature range if the application operates outside commercial limits. Verify that the SOIC package fits the available PCB footprint constraints.

Part Context

This part belongs to the Texas Instruments CD74HC238 family of high-speed CMOS decoders. It serves as a functional equivalent to other industry-standard 3-to-8 line decoders but includes specific enable configurations. The device is designed for general-purpose digital logic applications requiring reliable signal routing and address selection in complex electronic systems.
