Low-Voltage, Single and Dual Supply, Dual 4 to 1 Multiplexer Analog Switch with Enable
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 125Ω with a
+3.3V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only .01nA at +25
2.5nA at +85

C.
o
C or
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 ISL43840 is a dual 4 to 1 multiplexer device. Table 1 summarizes the performance of this part.
