The Intersil ISL84581 device contains precision,bidirecTIonal, analog switches configured as an 8-to-1mulTIplexer/demulTIplexer. It was designed to operate from asingle +2V to +12V single supply or from dual ±2V to ±6Vsupplies. The device has an inhibit pin to simultaneouslyopen all signal paths.The ISL84581 has an ON-resistance of 39Ω with a dual ±5Vsupply and 125Ω with a single +3.3V supply. Each switchcan handle rail-to-rail analog signals. The off-leakage currentis only 0.02nA at +25°C or 0.2nA at +85°C.All digital inputs have 0.8V to 2.4V logic thresholds, ensuringTTL/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 1summarizes the performance of the part.
