MAX4621CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4621CSE+ is a dual, high-speed analog switch featuring two single-pole/single-throw (SPST) normally open channels. It operates from a single positive supply (+4.5V to +36V) or bipolar supplies (±4.5V to ±18V). The device guarantees a low on-resistance of 5Ω maximum and maintains channel-to-channel matching within 0.5Ω. Key electrical parameters include turn-on time under 250ns, turn-off time under 200ns, and off-leakage current below 5nA at +85°C. It utilizes CMOS logic inputs compatible with TTL/CMOS standards and is housed in a 16-pin Narrow SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) against the datasheet ordering information. Confirm the 'E' suffix denotes the 16-pin Narrow SOIC package type. Ensure the '+'' suffix confirms lead-free compliance status as defined by the manufacturer's specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPST switching is required with low distortion and fast response times. Verify that the application voltage does not exceed the absolute maximum ratings of +44V between V+ and V-. Consider the thermal dissipation limits if operating near the upper temperature boundary.
