FSA1259A: Low-Voltage 1Ω Dual-SPST Analog Switch with Power-Off Isolation

The FSA1259A is a high-performance, dual, Single-Pole / Single-Throw (SPST) analog switch. The device features ultra-low RON of 1Ω at 4.5V VCC and operates over the wide VCC range of 1.65V to 5.50V.

The FSA1259A allows for reduced input thresholds on the select pins.

The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation.
