Table 1-9: Isolated Digital Input Electrical Specification
1.3.8 General Purpose Isolated Digital Output
Four isolated digital output channels are provided, such that, in the
common ground connection of digital output, as shown, when a 1
(logic high) is written by FPGA to a DO channel, sink current
passes through the transistors and the DO channel goes low, and
when a 0 (logic low) is written by FPGA to a DO channel, no cur-
rent passes through the transistors and the DO channel goes high.
