Overview
The SN65HVS882PWPR is an eight-channel digital-input serializer designed by Texas Instruments for high-channel density digital input modules in industrial automation and process control. This device interfaces between high-voltage signals on the field side and low-voltage signals on the controller side, making it ideal for applications requiring reliability and precision. It operates in conjunction with galvanic isolators and features current-limited inputs validated by internal debounce filters. The device is available in a 28-pin HTSSOP (Thin Shrink Small Outline Package) with a PowerPAD™ for efficient heat dissipation and is characterized for operation over a temperature range of -40°C to 125°C.
