ADM2491EBRWZ-REEL7 Description

Short technical summary and product information.

The ADM2491EBRWZ-REEL7 is a high-speed, ESD-protected, half-/full-duplex isolated RS-485 transceiver from Analog Devices. It operates at data rates up to 16 Mbps and offers ±8 kV ESD protection on its RS-485 input/output pins. This transceiver is configurable for half- or full-duplex operation and complies with ANSI TIA/EIA RS-485-A-1998 and ISO 8482: 1987(E) standards.

 

Designed for balanced transmission lines, the ADM2491E employs iCoupler technology to integrate a 3-channel isolator, a three-state differential line driver, and a differential input receiver. It supports 5 V or 3.3 V logic-side operation and requires an isolated 5 V supply for the bus side. The device includes current-limiting and thermal shutdown features for protection against output short circuits and bus contention.

 

This component is housed in a wide body, 16-lead SOIC package and is designed for surface mounting. Its operating temperature range is -40°C to +85°C, making it suitable for industrial field networks and multipoint data transmission systems. The receiver features an open-circuit, fail-safe design, and the device supports up to 32 nodes on the bus.
