MAX4651EUE-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4651EUE-T is a quad single-pole single-throw (SPST) normally closed analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single +1.8V to +5.5V supply and features a maximum on-resistance of 7Ω at 3V and 4Ω at 5V. The device provides rail-to-rail signal handling, low off-leakage current of 0.1nA at +25°C, and TTL/CMOS logic compatibility. Packaged in a 16-pin TSSOP, it supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity against official manufacturer documentation. Confirm that the ordering suffix 'T' indicates tape-and-reel packaging as specified in the datasheet. Ensure the part number matches the specific MAX4651 variant with normally closed switches. Check for RoHS compliance markings corresponding to the '+' designation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low voltage operation between 1.8V and 5.5V is required. Choose the MAX4651 specifically for normally closed switch configurations, distinguishing it from the MAX4652 (normally open) and MAX4653 (mixed). Consider the 16-pin TSSOP package for space-constrained PCB layouts requiring surface-mount assembly.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4651/MAX4652/MAX4653 family of low-voltage, 4Ω, quad SPST CMOS analog switches. The MAX4651 variant specifically provides four normally closed switches, whereas other family members offer different contact states. These devices are designed to replace mechanical relays in automated test equipment and applications requiring current switching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4651EUE+ is the lead-free equivalent of the non-compliant MAX4651EUE. Other package options within the same electrical specification include MAX4651EGE (16-pin QFN) and MAX4651ESE (16-pin SO). Verify pinout compatibility if substituting with different package types.
