DATASHEET ISL84781 FN6095 Rev 4.00 Ultra Low ON-Resistance, Low-Voltage, Single Supply, 8-to-1 Analog Multiplexer October 28, 2010 The Intersil ISL84781 device contains precision, bidirectional, Features analog switches configured as an 8-channel Pin Compatible Replacement for the MAX4781, and multiplexer/demultiplexer. It is designed to operate from a MAX4617 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 0.4 ON-resistance is 0.4 with a +3.0V supply and 0.55 with a - V+ = +1.8V . 0.55 single +1.8V supply. Each switch can handle rail-to-rail r Matching Between Channels 0.12 ON analog signals. The off-leakage current is only 4nA max at +25C or 40nA 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 ISL84781 is a 8-to-1 multiplexer device that is offered in a Fast Switching Action (V = +3V) S 16 Ld TSSOP package, and a 16 Ld thin QFN package. -t . 16ns ON Table 1 summarizes the performance of this family. -t 13ns OFF TABLE 1.
