MAX4634ETB

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4634ETB is a fast, low-voltage, 4-channel CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 4 ohms and operates within a single supply voltage range of 1.8V to 5.5V. The device includes four independent switches with turn-on and turn-off times of 18ns and 11ns respectively. It utilizes a 10-TDFN (3x3) surface-mount package with an exposed pad for thermal dissipation. Key electrical characteristics include a charge injection of 2pC, off-state leakage current of 100pA, and channel-to-channel matching of 100 milliohms. The component supports an operating temperature range from -40°C to +85°C.
