ISL43L210
Ultra Low ON-Resistance, +1.1V to +4.5V Single Supply, SPDT Analog Switch
FN6131 Rev 0.00 March 15, 2005
The Intersil ISL43L210 device is a low ON-resistance, low voltage, bidirectional, single pole/double throw (SPDT) analog switch designed to operate from a single +1.1V to +4.5V supply. Targeted applications include battery powered equipment that benefit from low on-resistance and fast switching speeds (tON = 7ns, tOFF = 3ns). 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.
