Description

The Intersil ISL84780 device 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. Targeted applications include battery-powered equipment that benefit from low on-resistance, and fast switching speeds (tON = 12ns, tOFF = 8ns). 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 family of parts may be used to mux-in additional functionality while reducing ASIC design risk. The ISL84780 is offered in small form factor packages, alleviating board space limitations. The ISL84780 is a committed Quad SPDT that consists of four normally open (NO) and four normally closed (NC) switches. This configuration can also be used as a diff dual 2- to-1 multiplexer/demultiplexer or a quad 2-to1 multiplexer/demultiplexer. The ISL84780 is pin compatible with the MAX4780.
