The DG2523 and DG2524 are four-channel single-pole double-throw (SPDT) analog switches. The DG2523 has two control inputs that each controls a pair of single-pole double-throw (SPDT). It is also known as a two-channel double-pole double-throw (DPDT) configuration. The DG2524 has an EN pin to enable the device when the logic is low. The parts are designed to operate from 1.8 V to 5.5 V single power rail. All switches conduct equally well in both directions, offering rail to rail signal witching and can be used both as multiplexers as well as de-multiplexers. 1.8 V to 5.5 V single supply operation
