MAX491ECSD+T Description

Short technical summary and product information.

The MAX491ECSD+T from Analog Devices (formerly Maxim Integrated) is a low-power transceiver designed for RS-485 and RS-422 communication protocols. It supports full-duplex communication and can achieve data rates up to 2.5Mbps.

 

This transceiver operates from a single +5V supply (4.75V to 5.25V) and is rated for an operating temperature range of 0°C to 70°C. It includes one driver and one receiver, with receiver hysteresis specified at 70mV. The device is protected against ±15kV electrostatic discharge (ESD) shocks.

 

Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount case, the MAX491ECSD+T is suitable for applications requiring robust serial communication in harsh environments. It draws minimal supply current, as low as 120µA when unloaded, and features short-circuit current limiting and thermal shutdown protection.
