The MAX488 is designed with reduced slew-rate drivers to minimize EMI and reduce reflections from improperly terminated cables, ensuring error-free data transmission at speeds up to 250kbps. The drivers are current-limited and feature thermal shutdown circuitry to protect against excessive power dissipation, placing the outputs into a high-impedance state when needed. The fail-safe feature on the receiver input guarantees a logic-high output in case of an open circuit. This transceiver enables full-duplex communications for various applications, including low-power RS-485 and RS-422 setups, level translation, and industrial-control networks.
Application: Low-Power RS-485 Transceivers, Low-Power RS-422 Transceivers, Level Translators, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks
