ET74HC238V

Overview

The ET74HC238V is a high-speed CMOS decoder circuit manufactured by Etek Microelectronics. It accepts a three-bit binary weighted address on input pins A0, A1, and A2 to decode signals. As part of the HC logic family, this component is designed for efficient signal routing in digital systems. The device operates as a decoder or demultiplexer, providing one-hot decoding capabilities suitable for various electronic applications requiring precise address selection.

Feature Summary

• High-speed CMOS technology for rapid signal processing
• Three-bit binary weighted address decoding capability
• Compatible with standard HC logic family interfaces

Applications

• Digital address decoding circuits
• Demultiplexing data streams
• Logic control systems

Procurement Notes

Verify the specific datasheet for the ET74HC238V directly from Etek Microelectronics to confirm pinout compatibility and electrical characteristics. Ensure that the operating voltage ranges and load requirements match your system design before integration. Cross-reference with official distributor listings to validate authenticity and current production status.

Selection Notes

Select this component when a compact, high-speed solution for three-to-eight line decoding is required within an HC-compatible ecosystem. Consider the package type and thermal performance relative to your PCB layout constraints. Verify that the input logic levels align with your system's voltage domains to ensure reliable operation without additional level shifting.

Part Context

This part belongs to the broader 74HC238 series of decoders produced by multiple manufacturers, including Toshiba, NXP, and Texas Instruments. While functionally similar to industry-standard equivalents, the Etek variant offers specific manufacturing attributes. It serves as a direct functional replacement for generic 74HC238 devices in designs where supply chain diversification or specific vendor preferences are prioritized.

Replacement Considerations

Generic 74HC238 parts from other vendors may serve as functional substitutes if pinouts and electrical specs align. Verify compatibility with specific variants like SN74HCS238 or 74HC238BQ only after confirming detailed parameter matching.
