ADM3491ARZ-REEL7 Description

Short technical summary and product information.

The ADM3491ARZ-REEL7 is a 3.3V low power differential line transceiver designed for RS-422 and RS-485 communication. It operates from a 3.3V supply and is interoperable with 5V logic. This full duplex transceiver features one driver and one receiver, supporting data rates up to 10 Mbps. It includes a shutdown mode that reduces supply current to 2 nA typical. The device is specified over the -40°C to +85°C temperature range. It is available in a 14-SOIC surface mount package. The ADM3491ARZ-REEL7 is suitable for low power RS-485/RS-422 applications such as telecom, industrial process control, and HVAC systems. It can drive up to 32 transceivers on the bus and has a common-mode range of -7V to +12V. The receiver hysteresis is 50 mV typical, and skew is 8 ns typical.
