ISL43681IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43681IR-T is a precision, bidirectional analog switch configured as an 8-channel multiplexer. It operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. The device features an on-resistance of 39Ω at ±5V and 125Ω at +3.3V. It includes inhibit pins to open all signal paths and a latch bar pin to lock the last switch address. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. Off-leakage current is 0.1nA at +25°C and 2.5nA at +85°C. The component is housed in a 20-lead 4x4mm QFN package.
