MAX4634ETB-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4634ETB-T is a single-channel, 4-to-1 multiplexer switch integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8V to 5.5V and features a maximum on-resistance of 4 ohms. The device includes two circuits with SPDT configurations in a 10-WFDFN package with an exposed pad. Key electrical parameters include a maximum charge injection of 2pC, off-state leakage current of 100pA, and channel capacitance values of 9pF. Switching times are specified at 14ns for turn-on and 6ns for turn-off, with a crosstalk performance of -67dB at 1MHz.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to confirm tape-and-reel packaging and temperature grade. Ensure compliance with RoHS directives if required by your application standards. Cross-reference with authorized distributors to confirm current availability status and lead times, as component lifecycle stages may affect procurement options.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single 4:1 multiplexer function is required within a compact surface-mount footprint. Consider the 4-ohm on-resistance and 1.8V to 5.5V supply range against your system's power and signal integrity requirements. Verify that the 10-TDFN package dimensions fit your PCB layout constraints and thermal management needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4634 series of CMOS analog switches, designed for low-voltage, high-speed applications.
