74HC238PW,112

Overview

The 74HC238PW,112 is a 3-to-8 line decoder and demultiplexer manufactured by Nexperia. It accepts three binary weighted address inputs (A0, A1, A2) and provides eight mutually exclusive active HIGH outputs (Y0 to Y7). The device operates with a supply voltage range of 2.0 V to 6.0 V and features three enable inputs: two active LOW (E1, E2) and one active HIGH (E3). All outputs remain LOW unless E1 and E2 are LOW and E3 is HIGH.

Feature Summary

• Demultiplexing capability using enable inputs as data strobes
• Multiple input enable configuration for easy parallel expansion
• High noise immunity and CMOS low power dissipation
• Active HIGH mutually exclusive outputs

Applications

• Memory chip select decoding
• Parallel expansion to 1-of-32 decoders
• Eight output demultiplexing

Procurement Notes

Verify the ordering suffix '112' corresponds to the TSSOP16 package (SOT403-1) in official documentation. Confirm the specific temperature range requirements match the datasheet specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed decoding or demultiplexing is required within a wide voltage range. Ensure the application utilizes active HIGH outputs and can accommodate the specific enable logic states defined in the functional description.

Part Context

This part belongs to the 74HC238 family of high-speed Si-gate CMOS devices. It is pin compatible with Low-Power Schottky TTL (LSTTL) standards. The PW variant specifically denotes the plastic thin shrink small outline package with 16 leads.

Replacement Considerations

The 74HCT238PW,115 serves as a direct functional replacement within the same package type, offering TTL-compatible input levels instead of CMOS levels while maintaining identical pinout and logical operations.
