Support is limited to customers who have already adopted these products.

The Intersil ISL43L840 device is a precision, bidirectional, analog switches configured as a dual 4-channel multiplexer/demultiplexer, designed to operate from a single +1. 6V to +3. 6V supply. ON resistance is 0. 5Ω with a +3V supply and 0. 62Ω with a single +1. 8V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 4nA max at +25°C and 30nA max at +85°C with a +3. 3V supply. All digital inputs are 1. 8V logic-compatible when using a single +3V supply. The ISL43L840 is a dual 4 to 1 multiplexer device that is offered in a 16 Ld TSSOP and 16 Ld 3x3 QFN packages.
