SN74S151N

Signal Switches, Multiplexers, Decoders Overview

The SN74S151N is an 8-line-to-1-line data selector and multiplexer manufactured by Texas Instruments. It belongs to the ALS/AS TTL logic family, providing complete binary decoding to select one of eight data sources. The device features a strobe input that forces the standard output (Y) high when active. It includes both true (Y) and complementary (W) outputs. The component is housed in a 20-pin Plastic Leaded Chip Carrier (PLCC) package.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'FN' or 'N' against the manufacturer's current datasheet to confirm pinout compatibility and package type. Ensure the logic family matches system requirements. Confirm RoHS compliance status if required by design specifications. Check for obsolescence notices before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring fast switching speeds typical of the AS/ALS TTL series. Consider the PLCC package constraints for PCB layout. Verify voltage levels match the system's 5V logic standards. Evaluate thermal dissipation requirements for the plastic package in enclosed environments.

Signal Switches, Multiplexers, Decoders Part Context

This part is part of the SN74xx151 family of 8-input multiplexers. It shares functional similarities with other variants like SN74LS151 but offers different speed and power characteristics due to its specific logic family technology. It serves as a fundamental building block for complex digital logic designs requiring data selection.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for direct equivalents such as SN74ALS151FN or SN74AS151FN from Texas Instruments. Verify pin compatibility with other manufacturers' 74151 variants. Ensure electrical parameters like propagation delay and supply current are within acceptable limits for the application.
