Analog Switches, Multiplexers, Demultiplexers datasheet and documents for FSA4157AL6X

FSA4157AL6X

Analog Switches, Multiplexers, Demultiplexers Overview

The FSA4157AL6X is a discontinued 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 maximum on-resistance of 1.15 Ohms at 4.5 V VCC. The device supports a maximum DC switch current of 200 mA and includes break-before-make enable circuitry. It utilizes a MicroPak-6 package (SIP6, Case 127EB) for surface-mount installation.
