Ultra Low ON-Resistance, Low Voltage, Single Supply, SPDT Analog Switch
The Intersil ISL84714 device is a low ON-resistance, low voltage, bidirectional, single pole/double throw (SPDT) analog switch designed to operate from a single +1.65V to +3.6V supply. Targeted applications include battery powered equipment that benefit from low on-resistance and fast switching speeds (tON = 7.5ns, tOFF = 2.9ns). The digital logic input is 1.8V CMOS 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 ISL84714 is offered in the 6 lead SC70 package, alleviating board space limitations. The ISL84714 is a committed SPDT that consist of one normally (NO) and one normally (NC) switch. This configuration can also be used as a 2-to-1 multiplexer.
