MAX337CUI+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX337CUI+ is a monolithic CMOS analog multiplexer featuring dual 8-channel configurations. It connects one of eight inputs to a common output via a 3-bit binary address and supports bidirectional signal flow. The device operates from single +4.5V to +30V or dual ±4.5V to ±20V supplies, with TTL-compatible control inputs. Key electrical parameters include a maximum on-resistance of 700Ω (single supply) or 500Ω (dual supply), off-leakage current under 1.25nA at extended temperatures, and typical charge injection of 10pC. Transition times range from 350ns to 600ns depending on the supply configuration.
