MAX4502CUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4502CUK-T is a single-pole/single-throw (SPST), low-voltage, single-supply CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally closed (NC) configuration and operates continuously with a single supply between +2V and +12V. The device handles Rail-to-Rail analog signals with an off-leakage current of only 1nA at +25°C or 10nA at +85°C. Digital inputs utilize 0.8V and 2.4V logic thresholds for TTL/CMOS compatibility at +5V. Electrical characteristics include a guaranteed on-resistance of 250Ω at +5V, charge injection of 10pC, and switching speeds of tON = 75ns and tOFF = 50ns. It is housed in a SOT23-5 package with an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUK-T' against official manufacturer documentation to confirm the SOT23-5 package, tape-and-reel delivery format, and commercial temperature range (0°C to +70°C). Ensure that the ordering information matches the latest datasheet revision to avoid discrepancies in electrical specifications or pinout configurations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4502CUK-T when a normally closed analog switch is required for low-voltage applications. Consider the SOT23-5 package for space-constrained designs. Verify that the +2V to +12V supply range and 250Ω on-resistance meet system requirements. Confirm that the 0°C to +70°C operating temperature range is suitable for the intended environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4502CUK-T belongs to the MAX4501/MAX4502 family of low-voltage, SPST, CMOS analog switches. While the MAX4501 offers a normally open (NO) configuration, the MAX4502 provides a normally closed (NC) state. Both devices share identical electrical characteristics and packaging options, differing primarily in their default switch state upon power-up or logic input deactivation.
