DATASHEET ISL43L841 FN6212 Rev 1.00 Ultra Low ON-Resistance, Low-Voltage, Single Supply, Differential 4 to 1 Analog June 30, 2006 Multiplexer The Intersil ISL43L841 device contains precision, Features bidirectional, analog switches configured as a differential Pb-Free Plus Anneal (RoHS Compliant) 4-channel multiplexer/demultiplexer. It is designed to operate from a single +1.65V to +4.5V supply. The device has an Pin Compatible Replacement for the MAX4782 and inhibit pin to simultaneously open all signal paths. With a MAX4618 supply voltage of 4.2V and logic high voltage of 2.85V at the ON Resistance (R ) ON logic inputs, the part draws only 20A max of ICC current. - V+ = +4.3V 0.47 ON resistance is 0.47 with a +4.3V supply and 0.65 with - V+ = +3.0V . 0.52 a single +1.8V supply. Each switch can handle rail to rail - V+ = +1.8V . 0.65 analog signals. A channel can handle 300mA of continuous R Matching Between Channels 0.12 ON current. The part has low quiescent power consumption of 0.23W max. R Flatness Across Signal Range . 0.056 ON Single Supply Operation +1.65V to +4.5V All digital inputs are 1.8V logic-compatible when using a single +3V supply. Low Power Consumption (PD) . <0.23W The ISL43L841 is a differential 4 to 1 multiplexer device that is Low ICC Current when VinH is not at the V+ Rail offered in a 16 Ld 3x3 TQFN package.
