Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering suffix 'G4' confirms RoHS compliance and lead-free status as specified by Texas Instruments. Ensure the package type matches the required PCB footprint, typically associated with the E suffix indicating a specific surface-mount or through-hole configuration depending on the full part code interpretation. Confirm availability status as distribution channels may list variants with different suffixes.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual 4-to-1 multiplexing is required with HCT logic compatibility. It serves as a direct replacement for standard 74HCT153 devices in designs needing wide temperature tolerance. Consider the pinout and package dimensions relative to existing board layouts. Verify input voltage levels align with the system's logic family to ensure proper interfacing without additional level shifting.

Signal Switches, Multiplexers, Decoders Part Context

This device is part of the Texas Instruments 74HCT series of logic integrated circuits.
