The SN65HVS883 is a 24-V, eight-channel, digital-input serializer for high-channel
density digital input modules of PC and PLC-based systems in industrial automation. In combination
with galvanic isolators, the device completes the interface between the 24-V sensor outputs of the
field-side and the low-voltage controller inputs at the control-side. Input signals provided by
EN60947-5-2 compliant 2-wire and 3-wire proximity switches are current-limited and then validated by internal debounce
filters. The input switching characteristic is 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 via a subsequent isolator into a serial PLC
input.
Cascading of multiple SN65HVS883 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. Input status is indicated via 3-mA constant current LED outputs. An external
precision resistor is required to set the internal reference current. The integrated voltage
regulator provides a 5-V output to supply low-power isolators. An internal supply voltage monitor
provides a chip-okay (CHOK) indication.
The SN65HVS883 comes in a 28-pin PWP PowerPAD™ package allowing for efficient heat dissipation. The
device is specified for operation at temperatures from –40°C to 85°C.
