AS1745 (AS1744 / AS1745) SPDT Analog Switches

The AS1744/AS1745 are high-speed, low-voltage, dual single-pole/double-throw (SPDT) analog switches. Fast switching speeds, low ON-resistance, and low power-consumption make these devices ideal for singlecell battery powered applications. These highly-reliable devices operate from a +1.8 to +5.5V supply, are differentiated by inverted logic, and support brea.
