Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the package type matches the application requirements, as the PWLE suffix indicates a specific plastic small-outline or similar variant depending on the specific datasheet revision, though often associated with surface mount, ensure compatibility with the intended PCB footprint. Confirm the logic family specifications align with the target system voltage levels. Check for automotive qualification if required, noting that standard AC parts may differ from Q1 variants.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 3-to-8 line decoding function with inverted outputs is required in the AC logic family. Ensure the system voltage falls within the 3 V to 5.5 V range. Consider the three enable inputs for complex enable schemes. Compare against SN74AC138 variants if different packaging or temperature ranges are needed.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Texas Instruments 74AC series of high-speed CMOS logic devices. It functions similarly to other 3-to-8 decoders like the SN74AC138 but may have specific packaging or minor electrical differences. It is distinct from the SN74AC11138N which uses a PDIP package, while the PWLE typically denotes a surface-mount package variant.

Signal Switches, Multiplexers, Decoders Replacement Considerations

SN74AC138PWRQ1 is a related automotive-grade variant in the same logic family. Verify pinout and electrical characteristics before substitution.
