MAX4601CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4601CPE is a quad SPST CMOS analog switch in a 16-pin Plastic DIP package. It features a maximum on-resistance of 2.5Ω with guaranteed matching and flatness of 0.5Ω over the signal range. The device handles rail-to-rail analog signals with an off-leakage current of 2.5nA max at +85°C. Operating from single supplies of +4.5V to +36V or dual supplies of ±4.5V to ±20V, it includes TTL/CMOS-compatible control inputs. Switching times are 160ns turn-on and 170ns turn-off under single-supply conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE' corresponds to the 0°C to +70°C temperature range and 16-PDIP package. Confirm that the NC configuration matches the design requirements, as the MAX4602 variant provides NO switches. Ensure supply sequencing follows manufacturer guidelines to prevent latch-up or damage during power-up.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low distortion and high reliability compared to mechanical relays. Verify that the 2.5Ω on-resistance meets the voltage drop requirements for the target signal levels. Consider the 160ns switching speed for timing constraints. Evaluate board space savings against the physical dimensions of the 16-PDIP package.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4601/MAX4602/MAX4603 family of quad analog switches. The MAX4601 specifically provides four normally closed switches, whereas the MAX4602 offers four normally open switches. The MAX4603 combines two NC and two NO switches. All variants share identical electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4602CPE provides the same electrical performance but with four normally open switches instead of normally closed.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic sense for the MAX4601?

The MAX4601 switches ON when the logic input is LOW (0) and OFF when the logic input is HIGH (1).

How does the MAX4601 handle overvoltage?

Internal diodes clamp signals exceeding V+ or V-. External blocking diodes can be added for protection if proper power-supply sequencing cannot be maintained.

What is the maximum continuous current rating?

The continuous current for COM_, NO_, and NC_ pins is rated at ±200mA.
