The SN65HVS882EVM is an evaluation module for evaluating SN65HVS882 digital input serializer. The SN65HVS882 is an 8 channel, digital input serializer for high channel density digital input modules in industrial automation. In combination with galvanic isolators the device completes the interface between the high voltage signals on the field side and the low voltage signals on the controller side. Input signals are current limited and then validated by internal debounce filters. With the addition of a few external components, the input switching characteristics can be configured in accordance with IEC61131-2 for Type 1, 2, and 3 sensor switches. Upon the application of load and clock signals, input data is latched in parallel into the shift register and afterwards clocked out serially. Cascading of multiple devices is possible by connecting the serial output of the leading device with the serial input of the following device, enabling the design of high channel count input modules.
● High input voltage up to 34V
● 0ms to 3ms selectable debounce filters
● 0.2mA to 5.2mA flexible input current limit
● Field pins protected to 15KV HBM ESD
● Output drivers for external status LEDs
● Cascadable in multiples of eight inputs
● SPI compatible interface
● Regulated 5V output for external isolator
● Over temperature indicator
●EVM is not intended for electromagnetic compatibility (EMC) tests
