The ISL84782 low-voltage single supply differential 4:1 analog switch has a low ON resistance, low leakage current and high voltage tolerance. It has precision, bidirectional analog switches configured as a differential 4-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.
The ISL84782 analog multiplexer provides precise switching with an on‑resistance of about 0.5 Ω at 3 V and 0.62 Ω at 1.8 V. It operates from a single supply of 1.6 V to 3.6 V, consumes less than 0.2 µW, and can handle up to 300 mA continuous current. The device is offered in 16‑lead TSSOP and 16‑lead 3×3 mm thin QFN packages.
The datasheet includes absolute maximum ratings, detailed electrical specifications for both 3 V and 1.8 V supply conditions, test circuits, and recommended protection methods. It also provides package dimension drawings and notes on RoHS‑compliant, Pb‑free manufacturing.
