说明

The SN65HVS885 is an eight channel, digital-input serializer for high-channel density digital input modules in industrial and building automation. Operating from a 5V supply the device accepts field input voltages of up to 34V. 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. Inputs signals are current limited and then validated by internal debounce filters.

With the addition of few external components, the input switching characteristic 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.
