FSA4157P6

Analog Switches, Multiplexers, Demultiplexers Overview

The FSA4157P6 is a discontinued Single Pole/Double Throw (SPDT) analog switch fabricated with sub-micron CMOS technology. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 1.15 Ω at 4.5 V. The device supports a DC switch current of 200 mA, with turn-on and turn-off times reaching 35 ns and 15 ns respectively. It utilizes an SC-70-6 package and includes break-before-make circuitry alongside TTL-compatible control inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This component has been officially discontinued by the manufacturer and is not recommended for new designs. Verification of availability should focus on surplus distributors or secondary market sources rather than standard manufacturing channels. Designers must confirm the authenticity of existing stock due to the end-of-life status.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Engineers should evaluate the FSA4157A variant if lower quiescent current is required when the control voltage is below the supply voltage. For applications requiring a wider low-voltage operating range starting at 1.65 V, this specific part remains the primary choice despite its discontinuation status. Package compatibility with SC-70-6 footprints should be verified during replacement selection.

Analog Switches, Multiplexers, Demultiplexers Part Context

The FSA4157P6 belongs to the FSA4157 series of low-voltage analog switches produced by onsemi. It shares functional similarities with the FSA4157A but differs in minimum operating voltage specifications. The P6 suffix indicates the SC-70-6 surface-mount packaging configuration used for space-saving implementations in portable devices.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative components require manual verification of pinout compatibility, electrical parameters, and package dimensions.
