ISL43840
Low-Voltage, Single and Dual Supply, Dual 4 to 1 Multiplexer Analog Switch with Enable
FN6056 Rev 2.00 Mar 13, 2006
The Intersil ISL43840 device is a precision, bidirectional, analog switches configured as a a dual 4 channel multiplexer/ demultiplexer designed to operate from a single +2V to +12V supply or from a 2V to 6V supply. The device has two enable bar pins to simultaneously open all signal paths of bank A and B.
ON resistance of 39 with a 5V supply and 125 with a +3.3V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only .01nA at +25°C or 2.5nA 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.
