Description
The Intersil ISL43L420 device is a low ON-resistance, low voltage, bidirectional, Quad SPDT (Dual DPDT) analog switch designed to operate from a single +1.1V to +4.5V supply. Targeted applications include battery-powered equipment that benefit from low RON (0.24?) and fast switching speeds (tON = 8ns, tOFF = 5ns). The digital logic input is 1.8V logic-compatible when using a single +3V supply. The ISL43L420 is a committed Quad SPDT that consists of four normally open (NO) and four normally (NC) switches. This configuration can also be used as a diff dual 2-to-1 multiplexer/demultiplexer or a dual 2-to1 multiplexer/demultiplexer. The ISL43L420 is pin compatible with the STG3699.
