FSA4157AP6X

Analog Switches, Multiplexers, Demultiplexers Overview

The FSA4157AP6X is a low-voltage, single-pole double-throw (SPDT) analog switch fabricated with sub-micron CMOS technology. It operates within a supply voltage range of 2.7 V to 5.5 V and features an ultra-low on-resistance (RON) of 1.15 Ω maximum at 4.5 V VCC. The device supports a maximum switch current of 200 mA DC and includes break-before-make circuitry for reliable signal routing. It utilizes a 6-lead SC-70 surface-mount package and offers TTL-compatible control inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for specific lot traceability codes on the marking diagram. Ensure storage conditions remain within specified limits to maintain reliability before assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when a 2.7 V minimum supply voltage is acceptable. The 'A' suffix indicates lower quiescent current characteristics compared to the standard variant. Verify that the SC-70 package dimensions fit the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the FSA4157 series of high-performance analog switches. It shares core functionality with the FSA4157 but differs in operating voltage thresholds and power consumption profiles. The series is designed for compact mobile applications requiring efficient signal management.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The FSA4157P6X serves as a functional alternative if the system supports a 1.65 V minimum supply voltage. Verify pin compatibility and ensure the replacement meets the required on-resistance specifications for the application.
