DESCRIPTION  
The SN65HVS881 is an eight 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. Multiple devices can be  
cascaded through a single serial port, reducing both the isolation channels and controller inputs required.  
Input status can be visually indicated via constant current LED outputs. The current limit on the inputs is set by a  
single external precision resistor. An integrated voltage regulator provides a 5V output to supply low-power  
isolators. An on-chip temperature sensor provides diagnostic information for graceful shutdown and system  
safety. An internal parity check for odd parity ensures trustworthy transmission of serial data to the system  
controller.  
The SN65HVS881 is available in a 28-pin PWP PowerPAD™ package, allowing for efficient heat dissipation. The  
device is characterized for operation at temperatures from –40°C to 125°C
