Product Summary
The MAX487CPA is a low-power transceiver for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The applications of the MAX487CPA include: (1)Low-Power RS-485 Transceivers; (2)Low-Power RS-422 Transceivers; (3)Level Translators; (4)Transceivers for EMI-Sensitive Applications; (5)Industrial-Control Local Area Networks.
