MAX4509ESE+T Description

Short technical summary and product information.

The MAX4509ESE+T is a dual 4-to-1 fault-protected analog multiplexer designed for various signal routing applications. It is pin-compatible with industry-standard DG509 devices.

 

This multiplexer features a maximum on-resistance of 400 Ohms, matched between channels to within 15 Ohms. It supports rail-to-rail signal handling and offers ±40V fault protection with power off and ±25V protection with supplies on. The device operates with dual supplies ranging from ±4.5V to ±20V or a single supply from +9V to +36V.

 

Digital inputs are TTL/CMOS-compatible. The MAX4509ESE+T has a fast fault-response time of 20ns. It is supplied in a 16-SOIC surface-mount package.

 

Applications include data acquisition systems, industrial and process control, avionics, signal routing, and redundant/backup systems.
