View Datasheet Manufacturer Site View Pricing & Stock

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.
