MAX4854HETE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4854HETE+ is a quad single-pole/single-throw (SPST) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2V to +5.5V supply and features four low on-resistance switches with a typical value of 7 Ω at VCC = 3V. The device provides overvoltage protection, entering high impedance when input signals exceed the supply rail. It includes 27.5pF on-capacitance and supports a -3dB bandwidth of 150MHz. The logic inputs are compatible with 1.8V logic levels, and the supply current is typically 10µA. It is housed in a space-saving 16-pin TQFN package with an exposed paddle.
