MAX4568EUK+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4568EUK+T is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +12V supply and features ±15kV ESD protection on the NO/NC terminals. The device provides an on-resistance of 70Ω at +5V and 120Ω at +3V, with a maximum match between channels of 2Ω and flatness of 4Ω. Off-leakage current is typically 0.5nA at +25°C. It utilizes TTL/CMOS-compatible logic thresholds and is housed in a 5-pin SOT23 package.
