MAX3292ESD

MAX3292ESD Description

The MAX3292ESD from Analog Devices Inc./Maxim Integrated is a high-performance RS422/RS485 transceiver designed for robust differential communication in industrial and embedded systems. Housed in a 14-pin SOIC package, this full-duplex transceiver integrates one driver and one receiver, supporting data rates up to 10Mbps. Operating within a 4.75V to 5.25V supply range, it ensures reliable signal transmission in noisy environments, thanks to its 35mV receiver hysteresis, which enhances noise immunity. The device is REACH unaffected and complies with EAR99 export control classifications, making it suitable for global deployments. Although marked obsolete, it remains a viable choice for legacy systems requiring dependable RS485/RS422 communication.
