MAX4651EUE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4651EUE is a low-voltage, quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features four normally closed switches in the TSSOP-16 package. The device offers a maximum on-resistance of 4Ω at +5V and 7Ω at +3V, with an on-resistance matching of 0.2Ω max and flatness of 0.8Ω max at +5V. Off-leakage current is specified at 0.1nA at +25°C. Typical turn-on and turn-off times are 20ns and 12ns respectively. The component supports rail-to-rail analog signals and is compatible with TTL/CMOS logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EUE' corresponds to the 16-pin TSSOP package and -40°C to +85°C temperature range. Confirm that the 'MAX4651' designation indicates the four normally closed switch configuration. Ensure compatibility with single-supply voltages between +1.8V and +5.5V for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch with normally closed default state is required. Compare against MAX4652 (normally open) and MAX4653 (mixed NO/NC) if different switching states are needed. Consider the TSSOP-16 package constraints and verify that the 4Ω on-resistance meets the signal integrity requirements for the specific load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4651EUE belongs to the MAX4651/MAX4652/MAX4653 family of low-voltage analog switches. These devices are designed as reliable alternatives to mechanical relays in automated test equipment and current-switching applications. The family shares identical electrical characteristics and pinouts, differing only in the internal switch contact states (NO vs NC).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4652EUE (four normally open switches) and MAX4653EUE (two normally open and two normally closed switches). Other packages such as MAX4651EGE (QFN) or MAX4651ESE (SO) offer the same electrical performance with different physical footprints.
