Overview
The SN65HVS880PWPR is a 24-V, eight-channel digital-input serializer designed by Texas Instruments for high-channel density digital input modules in industrial automation and process control systems. This device interfaces between 24-V sensor outputs on the field side and low-voltage controller inputs on the control side, often in conjunction with galvanic isolators. It supports input signals from EN60947-5-2 compliant 2- and 3-wire proximity switches and adheres to IEC61131-2 standards for Type 1, 2, and 3 sensor switches. The device features a SPI-compatible interface, selectable debounce filters, and adjustable current limits, making it versatile for various industrial applications.
