The MAX1481EUB+T is a full duplex, slew rate limited, low power RS485/RS422 transceiver in 10 pin μMAX package. This device is functionally equivalent to the industry standard MAX491 and 75180 and is designed for space constrained, full duplex RS422 applications. The reduced slew rate driver minimizes EMI and reduce reflections caused by improperly terminated cables allowing error-free data transmission up to 250Kbps. The driver output is short circuit current limited and is protected against excessive power dissipation by thermal-shutdown circuitry that places the driver outputs into a high impedance state. The receiver input has a fail-safe feature that provides a logic-high output if the input is open circuit.
Supply voltage range is 4.75V to 5.25V
Operating temperature range from -40°C to 85°C
One driver and one receiver
1/8 unit load receiver input impedance
Features receiver enable and driver enable function
