ISL43841
Low-Voltage, Single and Dual Supply, Dual
4 to 1 Multiplexer Analog Switch with
Latch
The Intersil ISL43841 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 a latch bar
pin to lock in the last switch address.
ON resistance of 39
Ω 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 0.1nA at +25oC or
2.5nA at +85oC.
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 ISL43841 is a dual 4 to 1 multiplexer device. Table 1
summarizes the performance of this part.
