CD74HC238M96

Signal Switches, Multiplexers, Decoders Overview

The CD74HC238M96 is a high-speed CMOS decoder/demultiplexer manufactured by Texas Instruments. It features a single 3-to-8 line decoding circuit with active-low outputs in the HC variant, housed in a 16-SOIC package. The device operates on a single power supply ranging from 2V to 6V and supports an extended operating temperature range from -55°C to +125°C. It provides three binary address inputs (A0, A1, A2) and includes two active-low enable inputs (E1, E2) and one active-high enable input (E3) to facilitate cascading applications.

• Cascaded decoding architectures

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix M96 against official datasheets to confirm tape-and-reel packaging specifications. Ensure the design requires the HC logic family voltage range rather than HCT compatibility. Confirm that the 16-SOIC footprint matches the target PCB layout constraints before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a standard 3-to-8 decoder with active-low outputs is required within a 2V to 6V supply window. The HC series offers speed comparable to low-power Schottky TTL while maintaining CMOS power efficiency. Verify that the SOIC package dimensions fit the available board space and thermal requirements.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Texas Instruments CD74HC238 series of high-speed silicon-gate CMOS decoders. It shares functional similarities with the non-inverting CD74HC138 but differs in output polarity. The M96 suffix typically indicates a specific reel quantity or packaging configuration distinct from tube-packaged variants like the PW or MT versions.

Signal Switches, Multiplexers, Decoders Replacement Considerations

CD74HC138M96 serves as a direct alternative if non-inverting outputs are acceptable instead of the standard active-low configuration.
