DATASHEET ISL43L220 FN6093 Rev 2.00 Ultra Low ON-Resistance, Low Voltage, Single Supply, Dual SPDT Analog Switch Feb 27, 2013 The Intersil ISL43L220 device is a low ON-resistance, low Features voltage, bidirectional, dual single-pole/double-throw (SPDT) Pb-Free (RoHS Compliant) analog switch designed to operate from a single +1.1V to +4.5V supply. Targeted applications include battery powered ON Resistance (R ) ON equipment that benefit from low R (0.22 and fast ON - V+ = +4.3V . 0.22 switching speeds (t = 11ns, t = 5ns). The digital logic ON OFF - V+ = +3.0V . 0.26 input is 1.8V logic-compatible when using a single +3V supply. - V+ = +1.8V 0.5 Cell phones, for example, often face ASIC functionality R Matching Between Channels 0.03 ON limitations. The number of analog input or GPIO pins may be R Flatness Across Signal Range 0.03 ON limited and digital geometries are not well suited to analog switch performance. This part may be used to mux-in Single Supply Operation . +1.1V to +4.5V additional functionality while reducing ASIC design risk. The Low Power Consumption (PD) <0.3W ISL43L220 is offered in a small form factor package, Fast Switching Action (V+ = +4.3V) alleviating board space limitations. -t . 11ns ON The ISL43L220 is a committed dual single-pole/double-throw -t 5ns OFF (SPDT) that consist of two normally open (NO) and two normally closed (NC) switches. This configuration can also be Guaranteed Break-Before-Make used as a dual 2-to-1 multiplexer. The ISL43L220 is pin 1.8V Logic Compatible (+3V supply) compatible with the MAX4684 and MAX4685.
