FSA3157L6X

Analog Switches, Multiplexers, Demultiplexers Overview

The FSA3157L6X is a single-pole/double-throw (SPDT) analog switch fabricated using advanced sub-micron CMOS technology. It operates within a supply voltage range of 1.65 V to 5.5 V, supporting rail-to-rail signal handling. The device features a maximum on-resistance of less than 10 Ω at 3.3 V and a 3 dB bandwidth of 250 MHz. Key timing parameters include a maximum propagation delay of 3.5 ns and a maximum power-down leakage current of 1 µA. It utilizes a MicroPak-6 surface-mount package with dimensions of 1.45 x 1 x 0.5 mm and functions across an operating temperature range of -40 °C to +85 °C.
