MC74HC238ADR2G

Signal Switches, Multiplexers, Decoders Overview

The MC74HC238ADR2G is a high-performance silicon-gate CMOS 1-of-8 decoder/demultiplexer manufactured by onsemi. It features three-bit address inputs (A0, A1, A2) and three chip select inputs (CS1, CS2, CS3) to facilitate demultiplexing, cascading, and chip-selecting functions. The device operates within a supply voltage range of 2.0 V to 6.0 V and provides active-high decoded outputs. It is housed in a SOIC-16 surface-mount package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Decodes three-bit addresses to one of eight active-high outputs
• Includes three chip select inputs for demultiplexing and cascading
• Outputs directly interface with CMOS, NMOS, and TTL logic families

Signal Switches, Multiplexers, Decoders Applications

• Demultiplexing data streams using address selection
• Cascading multiple decoder units for expanded addressing
• Chip-selecting functions in memory or peripheral systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'R2G' confirms the SOIC-16 tape and reel packaging configuration. Ensure compatibility with standard CMOS output interfaces or LSTTL outputs when pull-up resistors are utilized. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer documentation.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel 1-of-8 decoding function is required with active-high outputs. Consider the HC series characteristics for operation between 2.0 V and 6.0 V. Verify that the SOIC-16 package dimensions align with the target PCB layout requirements.
