ISL54057 Data Sheet September 29, 2006 FN6379.0 Ultra Low ON-Resistance, Low-Voltage, Features Single Supply, Differential 4 to 1 Analog Pb-Free Plus Anneal Available (RoHS Compliant) Multiplexer ON Resistance (R ) ON The Intersil ISL54057 device contains precision, bidirectional, - V+ = +3.0V . 0.41 analog switches configured as a differential 4-channel - V+ = +1.8V . 0.61 multiplexer/demultiplexer, designed to operate from a single R Matching Between Channels 0.09 +1.6V to +3.6V supply. The devices have an inhibit pin to ON simultaneously open all signal paths. R Flatness Across Signal Range 0.07 ON ON resistance is 0.41 with a +3V supply and 0.61 with a Single Supply Operation . +1.6V to +3.6V single +1.8V supply. Each switch can handle rail to rail Low Power Consumption (PD) . <0.18W analog signals. The off-leakage current is only 4nA max at +25C or 35nA max at +85C with a +3.3V supply. Fast Switching Action (V = +3V) S -t 27ns ON All digital inputs are 1.8V logic-compatible when using a . 18ns -t single +3V supply.
