Overview: ® ISL43L410
Data Sheet July 28, 2006 FN6090.2 Ultra Low ON-Resistance, Low Voltage, Single Supply, DPDT Analog Switch
The Intersil ISL43L410 device is a low ON-resistance, low voltage, bidirectional, double-pole/double-throw (DPDT) analog switch designed to operate from a single +1.65V to +3.6V supply. It is equipped with an inhibit pin to simultaneously open all signal paths. Targeted applications include battery powered equipment that benefit from low RON (0.25Ω) and fast switching speeds (tON = 12ns, tOFF = 5ns). The digital logic input is 1.8V logiccompatible 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 ISL43L410 is offered in small form factor packages, alleviating board space limitations. The ISL43L410 is a committed double-pole/double-throw (DPDT) that consists of two normally open (NO) and two normally closed (NC) switches. This configuration is perfect www.DataSheet4U.com for use in differential 2-to-1 multiplexer applications.
