资 源 简 介
The SN65HVS882 is an eight channel, digital-input serializer for high-channel density digital input modules inindustrial 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.
