MAX337EWI+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX337EWI+ is a monolithic CMOS analog multiplexer featuring two independent 8-channel switches in a 28-pin Wide SO package. It connects one of eight inputs to a common output via a 3-bit binary address and supports single (+4.5V to +30V) or dual (±4.5V to ±20V) supplies. Key electrical parameters include a maximum on-resistance of 700Ω, off-leakage current under 1.25nA at extended temperatures, and transition times up to 600ns. The device provides over 2000V ESD protection and operates within a temperature range of -40°C to +85°C.
