Ultra Low ON-Resistance, +1.65V to +4.5V, Single Supply, Dual SPDT Analog Switch

The Intersil ISL8484 device is a low ON-resistance, low voltage, bidirectional, dual single-pole/double-throw (SPDT) analog switch designed to operate from a single +1.65V to +4.5V supply. Targeted applications include battery powered equipment that benefit from low rON (0.29Ω) and fast switching speeds (tON = 40ns, tOFF = 20ns). The digital logic input is 1.8V logic-compatible when using a single +3V supply.
