MAX491CPD Description

Short technical summary and product information.

The MAX491CPD from Analog Devices is a low-power transceiver designed for RS-485 and RS-422 communication. This device integrates one driver and one receiver, supporting full-duplex communication. It is capable of transmitting data at speeds up to 2.5Mbps due to its non-limited slew rate drivers.

 

The transceiver operates from a single 5V supply, with a voltage range of 4.75V to 5.25V. It features a receiver hysteresis of 70mV and operates within a temperature range of 0°C to 70°C. The drivers are protected against short-circuit conditions and excessive power dissipation through thermal shutdown circuitry.

 

Designed for applications sensitive to EMI, the MAX491CPD minimizes electromagnetic interference. It is suitable for industrial-control local area networks and general level translation tasks. The receiver input includes a fail-safe feature, ensuring a logic-high output if the input is open-circuited.

 

This component is housed in a 14-PDIP package and utilizes through-hole mounting. Its applications include low-power RS-485 and RS-422 communication systems, level translators, and EMI-sensitive communication links.
