ADM485ARZ

ADM485ARZ Description

The ADM485ARZ from Analog Devices Inc. is a robust half-duplex RS-485/RS-422 transceiver designed for high-speed data communication in industrial and commercial environments. Housed in an 8-pin SOIC package, this surface-mount IC integrates one driver and one receiver, supporting data rates up to 5 Mbps. Operating within a 4.75V to 5.25V supply range, it ensures reliable performance in noisy conditions, thanks to its 70 mV receiver hysteresis, which enhances noise immunity. Compliant with ROHS3 and REACH standards, the ADM485ARZ is ideal for applications requiring robust differential signaling and long-distance communication.
