Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-20 package type when ordering. Ensure the required operating temperature range aligns with the -40 °C to +85 °C specification. Confirm that the 5 V supply voltage requirement matches the system design constraints before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple 2-input signals require selective routing to a single output line. The ACT series offers faster switching speeds compared to standard 74LS equivalents. Verify that the input voltage levels are compatible with the driving logic family to ensure proper logic threshold recognition.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74ACT logic family, which combines the high-speed performance of Advanced CMOS technology with the compatibility of standard TTL inputs. The 11157 designation specifically identifies the quadruple 2-to-1 multiplexer function within this series.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for direct pin-compatible alternatives such as the 74AC11157 or other 74ACT series multiplexers from Texas Instruments. Ensure substitute parts maintain the same 20-pin PDIP footprint and electrical characteristics.
