ISL43L420
Ultra Low ON-Resistance, +1.1V to +4.5V Single Supply, Quad SPDT (Dual DPDT) Analog Switch
FN6098 Rev 1.00 February 18, 2005
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.
