MAX14890E - Incremental Encoder Interface for RS-422, HTL, and TTL with Digital Inputs - 传感器与传感器接口 - Industry's Most Robust Quad RS-422/TTL/HTL Receivers + 2 DI - 美信半导体
The MAX14890E incremental encoder receiver contains four differential receivers and two single-ended receivers.
The differential receivers can be operated in RS-422 or differential high-threshold logic (HTL) modes and are optionally configurable for single-ended TTL/HTL operation. The MAX14890E features a wide common mode input range of -20V to +20V in RS-422 mode.
The auxiliary IEC 61131-2 Type-1/Type-3 digital inputs are designed for operation with switches or proximity sensors and can be individually configured for TTL operation.
All receiver input signals are fault protected to voltage shorts in the ±40V range. Per channel fault detection provides warning of irregular conditions such as small differential signals, shorts, opens, overvoltages, and undervoltages.
The MAX14890E features a pin-selectable SPI or parallel-logic interface. SPI control provides detailed diagnostics and individual configurations for receivers.
The MAX14890E is available in a 32-pin TQFN-EP (5mm x 5mm) and operates over the -40°C to +125°C temperature range.
