MAX4603EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4603EPE is a quad single-pole single-throw (SPST) CMOS analog switch featuring two normally open and two normally closed channels. It operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device guarantees a maximum on-resistance of 2.5Ω with a channel-to-channel match of 0.5Ω max and flatness of 0.5Ω max over the signal range. Electrical characteristics include a turn-on time of 160ns, turn-off time of 170ns, charge injection of 20pC, and off-leakage current of 1nA max at +85°C. It is housed in a 16-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPE' corresponds to the -40°C to +85°C temperature range and 16-PDIP package configuration. Confirm RoHS compliance status as indicated by the '+' designation. Check for obsolescence notices or last-time-buy dates directly from Analog Devices/Maxim Integrated documentation before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when mixed normally open and normally closed switching functions are required within a single package. Ensure the application signal levels remain within the specified rail-to-rail limits. Verify that the 2.5Ω on-resistance meets the system's insertion loss requirements compared to higher-resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4601/MAX4602/MAX4603 family of quad SPST CMOS analog switches. While the MAX4601 provides four normally closed switches and the MAX4602 offers four normally open switches, the MAX4603 uniquely combines two NC and two NO switches. All variants share identical electrical performance specifications regarding resistance, leakage, and speed.
