Automotive Single Supply, SPDT Analog Switch

The Intersil ISL76123 device is a small precision, bidirectional, single-pole/double throw (SPDT) analog switch, designed to operate from a single +2.7V to +12V supply. The device is supplied in a 6 Ld SOT-23 package. Targeted applications include automotive battery powered systems that can benefit from the device’s low power consumption (5µW), low leakage currents (3nA max), and fast switching speeds (tON = 28ns, tOFF = 20ns). This device will often find use in infotainment systems to “mux - in” additional functions to GPIO pins on SOCs.
