DATASHEET ISL84782 FN6097 Rev 3.00 Ultra Low ON-Resistance, Low-Voltage, Single Supply, Differential 4 to 1 Analog November 17, 2004 Multiplexer The Intersil ISL84782 device contains precision, bidirectional, Features analog switches configured as a differential 4-channel Pin Compatible Replacement for the MAX4782 and multiplexer/demultiplexer. It is designed to operate from a MAX4618 single +1.6V to +3.6V supply. The device has an inhibit pin to simultaneously open all signal paths. ON Resistance (R ) ON - V+ = +3.0V . 0.5 ON resistance is 0.5 with a +3V supply and 0.62 with a - V+ = +1.8V 0.62 single +1.8V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 4nA max at R Matching Between Channels 0.12 ON +25C and 30nA max at +85C with a +3.3V supply. R Flatness Across Signal Range 0.056 ON All digital inputs are 1.8V logic-compatible when using a Single Supply Operation . +1.6V to +3.6V single +3V supply. Low Power Consumption (PD) <0.2W The ISL84782 is a differential 4 to 1 multiplexer device that is Fast Switching Action (V = +3V) S offered in a 16 Ld TSSOP package and a 16 Ld thin QFN -t . 16ns package.
