The MAX491ECPD is a low-power transceiver for RS-485 and RS-422 communications, suitable for harsh environments. It features one driver and one receiver, supporting full duplex communication at data rates up to 2.5Mbps. The device operates from a single +5V supply and includes protection against ±15kV electrostatic discharge (ESD) shocks.
Key electrical characteristics include a supply voltage range of 4.75V to 5.25V and a receiver hysteresis of 70mV. The transceiver draws a low supply current of 120µA when unloaded and can enter a low-current shutdown mode consuming only 0.5µA. Drivers are short-circuit current limited and protected by thermal shutdown circuitry.
This transceiver is available in a 14-PDIP package and is designed for through-hole mounting. Its robust design makes it suitable for applications requiring reliable data transmission in demanding conditions.
