DATASHEET ISL84581 FN6416 Rev 3.00 Low-Voltage, Single and Dual Supply, 8-to-1 Multiplexer April 13, 2009 The Intersil ISL84581 device contains precision, Features bidirectional, analog switches configured as an 8-to-1 Fully Specified at 3.3V, 5V, 5V, and 12V Supplies for 10% multiplexer/demultiplexer. It was designed to operate from a Tolerances single +2V to +12V single supply or from dual 2V to 6V supplies. The device has an inhibit pin to simultaneously ON-Resistance (r ) Max, V = 4.5V . 50 ON S open all signal paths. ON-Resistance (r ) Max, V = +3V 155 ON S The ISL84581 has an ON-resistance of 39 with a dual 5V r Matching Between Channels, V = 5V . <2 ON S supply and 125 with a single +3.3V supply. Each switch Low Charge Injection, V = 5V . 1pC (Max) S can handle rail-to-rail analog signals. The off-leakage current is only 0.02nA at +25C or 0.2nA at +85C. Single Supply Operation . +2V to +12V All digital inputs have 0.8V to 2.4V logic thresholds, ensuring Dual Supply Operation . 2V to 6V TTL/CMOS logic compatibility when using a single 3.3V or Fast Switching Action (V = +5V) S +5V supply or dual 5V supplies. -t 38ns ON The ISL84581 is a single 8-to-1 multiplexer device.
