The Intersil ISL43681 and ISL43741 devices are precision, bidirectional, analog switches configured as an 8 channel and a differential 4 channel multiplexer/demultiplexer.
The Intersil ISL43681 and ISL43741 are precision, bidirectional analog switches configured as an 8‑channel and a differential 4‑channel multiplexer/demultiplexer. They operate from a single +2 V to +12 V supply or dual +2 V to +6 V supplies and include inhibit and latch pins for control.
The document provides detailed electrical specifications, absolute maximum ratings, pinout diagrams, package dimensions (20‑lead 4 × 4 mm QFN), and typical performance curves such as on‑resistance, charge injection and crosstalk. Application notes and handling cautions are also included.

They can operate from a single +2 V to +12 V supply or from dual +2 V to +6 V supplies.
It is supplied in a 20‑lead 4 × 4 mm QFN package.
They are sensitive to electrostatic discharge; proper IC handling procedures must be followed.
