JSMSEMI MAX3085ESA+T-JSM

The MAX3085ESA for RS-485/RS-422 communication is a high-speed half-duplex transceiver containing one driver and one receiver. It features ±15kV human body model ESD protection and a failsafe circuit that ensures a logic-high output when the receiver input is open or shorted. If all drivers connected to a terminated bus are disabled (high-impedance), the receiver will output a logic high. The MAX3085ESA incorporates a slew-rate-limited driver to reduce EMI and reflections caused by improperly terminated cables, enabling error-free data transmission at up to 1Mbps. In addition, the MAX3085ESA receiver features 1/8 unit load input impedance, allowing up to 256 transceivers to be connected on the bus, and operates over a -40°C to 85°C temperature range.
