Overview: DATASHEET ISL84581
Low-Voltage, Single and Dual Supply, 8-to-1 Multiplexer FN6416 Rev 3.00 April 13, 2009 The Intersil ISL84581 device contains precision, bidirectional, analog switches configured as an 8-to-1 multiplexer/demultiplexer. It was designed to operate from a single +2V to +12V single supply or from dual ±2V to ±6V supplies. The device has an inhibit pin to simultaneously open all signal paths. The ISL84581 has an ON-resistance of 39 with a dual ±5V supply and 125 with a single +3.3V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0.02nA at +25°C or 0.2nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using a single 3.3V or +5V supply or dual ±5V supplies. The ISL84581 is a single 8-to-1 multiplexer device. Table 1 summarizes the performance of the part.
