RS-485 bus transceiver for 5V industrial links
The Maxim Integrated MAX1487ECSA+ is a half-duplex transceiver with a single driver and single receiver, rated for signaling up to 2.5 Mbps. It operates from a 4.75 V to 5.25 V supply and includes 70 mV of receiver hysteresis.
What the 2.5 Mbps data rate and 70 mV hysteresis mean for your bus
At 2.5 Mbps, the receiver hysteresis of 70 mV provides a clean logic threshold on a differential bus that may see common-mode shifts or reflections.
It remains a current-production part with no last-time-buy notice.
