MAX4663CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4663CPE+ is a quad, single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Plastic DIP package. It integrates two normally open and two normally closed switches with a maximum on-resistance of 2.5Ω. The device supports single supplies from +4.5V to +36V or dual supplies from ±4.5V to ±20V. Key electrical parameters include an off-leakage current of 5nA max at +85°C, a turn-on time of 275ns, and a turn-off time of 175ns under dual supply conditions. It features guaranteed break-before-make switching and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the 'P' suffix corresponds to the 16-pin Plastic DIP package. Ensure the datasheet revision matches the required specifications for your design constraints.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and high reliability are required compared to mechanical relays. Verify that the 2.5Ω on-resistance meets the signal integrity requirements. Ensure the operating environment stays within the 0°C to +70°C limit specified for the C-grade variant.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4661/MAX4662/MAX4663 family of quad analog switches. While the MAX4661 offers four normally closed switches and the MAX4662 provides four normally open switches, the MAX4663 uniquely combines two of each type with guaranteed break-before-make timing.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include the MAX4661CPE+ and MAX4662CPE+. These parts share identical pinouts and electrical characteristics but differ in switch configuration (all NC or all NO).

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance flatness for this device?

The on-resistance flatness is guaranteed to be 0.5Ω max over the specified signal range.

How does the MAX4663 handle switching transitions?

It features guaranteed break-before-make switching, ensuring one switch opens before the other closes to prevent short circuits.

Is the logic supply voltage independent of the analog supply?

Yes, a separate logic supply pin (VL) guarantees TTL/CMOS logic compatibility regardless of the analog supply voltage.
