ISL84780 is an Intersil low voltage, single-supply, quad 2:1 analog multiplexer.
The Intersil ISL84780 is a low ON-resistance, low voltage, bidirectional, Quad SPDT (Dual DPDT) analog switch designed to operate from a single +1.6V to +3.6V supply. It is a committed Quad SPDT that consists of four normally open (NO) and four normally closed (NC) switches, offering configurations for dual 2-to-1 multiplexers or quad 2-to-1 multiplexers. The device is pin compatible with the MAX4780.
