Ultra Low ON-Resistance, +1.1V To +4.5V Single Supply, Quad SPDT (Dual DPDT) Analog Switch

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.
Cell phones, for example, often face ASIC functionality limitations. The number of Analog input or GPIO pins may be limited and digital geometries are not well suited to Analog Switch performance. This part may be used to mux-in additional functionality while reducing ASIC design risk. The ISL43L420 is offered in a small form factor package, alleviating board space limitations.
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.
