The ISL84516 and ISL84517 devices are precision, analog switches designed to operate from ±1. 5V to ±6V supplies. Targeted applications include battery powered equipment that benefit from the devices' low power consumption (350mW), low leakage currents, and fast switching speeds. Additionally, excellent RON flatness maintains signal fidelity over the whole input range, while micro packaging alleviates board space limitations. The ISL8451X are single-pole/single-throw (SPST) switches, with the ISL84516 being normally open (NO), and the ISL84517 being normally closed (NC).
