ISL43231 Low-Voltage, Single and Dual Supply, Triple SPDT Analog Switch

The Intersil ISL43231 device is a precision, bidirectional, analog switch configured as a a triple single pole/double throw (SPDT) switch, designed to operate from a single +2V to +12V supply or from a ±2V to ±6V supply. The device has an inhibit and inhibit bar pin to simultaneously open all signal paths. The device also has a latch bar pin to lock in the last switch address.

ON resistance of 39Ω 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 +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.

The ISL43231 is a committed triple SPDT, which is perfect for use in 2-to-1 multiplexer applications.
