ISL84781IRZ-T - Renesas Electronics

Description: The Intersil ISL84781 device contains precision, bidirectional, analog switches configured as an 8-channel multiplexer/demultiplexer. It is designed to operate from a single +1. 6V to +3. 6V supply. The device has an inhibit pin to simultaneously open all signal paths. ON-resistance is 0. 4Ω with a +3. 0V supply and 0. 55Ω 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 or 40nA max at +85°C with a +3. 3V supply. All digital in
