MAX14891EATP+

MAX14891EATP+ is a quad fault-protected RS-485/RS-422 receiver. It is ideal for applications requiring high data rates and reduced noise in rugged environments. Each receiver features a wide common-mode input range of -20V to +20V and is guaranteed to receive data at speeds up to 35Mbps. All receiver inputs are fault-protected against voltage shorts in the ±40V range. Per-channel fault detection provides warning of irregular conditions, such as short circuits and open connections. Applications include encoder interfaces, motor controllers, servo control commutation.

• Switching rates up to 35Mbps, 1.62V to 5.5V logic interface
• Open-wire and short-circuit detection, overvoltage and undervoltage fault detection
• Integrated protection ensures robust communication
• Supply voltage range from 4.5V to 5.5V
• Supply current is 9mA typical at (outputs not switching, no load, TA = +25°C)
• Receiver propagation delay is 25ns maximum at (CL = 15pF, VID = ±3V)
• Receiver channel-to-channel skew is 8ns maximum at (CL = 15pF, VID = ±3V)
• Differential input hysteresis is 230mV typical at (-20V ≤ VCM ≤ +20V)
• Single-ended input current is -170μA typical at (VCC = 0V or 5V, VIN = -10V)
• Operating temperature range from -40°C to +125°C, 20-lead TQFN-EP package
