Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix M96 against the manufacturer datasheet to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS3 compliance requirements as specified in the environmental classification. Confirm that the 16-SOIC package dimensions align with the target PCB footprint constraints before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single 3-to-8 decoder is required within the HCT logic family. It offers speed comparable to Low-Power Schottky TTL while maintaining CMOS power efficiency. Verify that the 4.5 V to 5.5 V supply voltage range matches the system design specifications and that the industrial temperature range suits the operational environment.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CD74HCT series of high-speed silicon-gate CMOS logic devices produced by Texas Instruments. The series is designed to provide performance similar to Low-Power Schottky TTL logic but with lower power consumption typical of CMOS technology. The CD74HCT138 variant specifically addresses the need for efficient 3-to-8 decoding in digital systems.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include CD74HC138M96 and CD74HCT138E4. Verify pinout compatibility and ensure that the alternative part number maintains the same 16-SOIC package and electrical characteristics.
