Overview

High Flexibility Simplifies Design
- Switching Rates up to 35Mbps
- 1.62V to 5.5V Logic Interface
Integrated Fault Detection Reduces Downtime
- Open-Wire and Short-Circuit Detection
- Overvoltage and Undervoltage Fault Detection
Integrated Protection Ensures Robust Communication
- ±40V Fault Protection Range
- ±20V Common Mode Range
- ±25kV HBM ESD
- ±7kV Air-Gap IEC 61000-4-2 ESD
- ±10kV Contact IEC 61000-4-2 ESD
- -40°C to +125°C Operating Temperature Range

The MAX14891E quad fault-protected RS-485/RS-422 receiver 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.

The MAX14891E is available in a 20-pin TQFN-EP (4mm x 4mm) and operates over the -40°C to +125°C temperature range.
