The TS3A5018 device is a quad single-pole double-throw (SPDT) analog switch that is designed to operate from 1.8 V to 3.6V. This device can handle digital and analog signals, and signals up to 4.6vdc can be transmitted in either direction.
To use this device, you are required to attach voltage from 1.8v to 3.6v for VCC and connect ground to power source ground. Connect EN pin to ground to enable the device. Your input signal as on a typical switch is located on CM1-4 and output can be NC1-4 for normally closed contacts and NO1-4 for normally open contacts. You are required to set IN pin to either 3.3v or ground to toggle the switches from Normally Closed to Normally Open state. Unfortunely this single pin controls the switch for all four, so you might have to get creative with it, we suggest not-gates or logic gates to get the desired output.
