MAX4645EUK+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4645EUK+T is a single-pole, single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. It operates from a +1.8V to +5.5V single supply and features a typical on-resistance of 2.5Ω at +5V. The device handles Rail-to-Rail analog signals with an off-leakage current of 0.25nA maximum at +25°C. Switching speeds include a turn-on time of 12ns and a turn-off time of 8ns. It is housed in a 5-pin SOT-23 package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance flatness and fast switching are critical. It is suitable for replacing mechanical relays in automated test equipment. Consider the single-supply voltage range and logic compatibility requirements during circuit design to ensure proper interfacing with control signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4645/MAX4646 family of fast, low-voltage analog switches. The MAX4645 variant functions as a normally open switch, while the MAX4646 is normally closed. Both share identical electrical characteristics and packaging options, differing only in their default switch state configuration.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4645 and MAX4646?

The MAX4645 is a normally open (NO) switch, whereas the MAX4646 is a normally closed (NC) switch. All other electrical specifications and pin configurations remain identical.

Can the MAX4645EUK+T handle signals outside the supply rails?

No, the device processes analog signals within the supply voltage range (GND to V+). Signals exceeding these limits are clamped by internal diodes.
