MAX14890EATJ+T

Drivers, Receivers, Transceivers Overview

The MAX14890E is an incremental encoder receiver featuring four differential receivers and two single-ended receivers. It supports RS-422, HTL, and TTL modes with a VCC supply of 4.5V to 5.5V and logic voltage VL from 1.62V to 5.5V. The device operates over a -40°C to +125°C temperature range in a 32-pin TQFN-EP (5mm x 5mm) package. RS-422 data rates reach up to 35Mbps, while HTL and TTL switching rates are up to 400kHz. Inputs withstand ±40V fault protection, and ESD ratings include ±7kV air-gap and ±10kV contact discharge.
