The OP7817 (also named OP7817-2) provides 16 push-pull digital output signals with specific voltage conditioning. All outputs are updated individually by the OP7000 or OP7000V2 Primary FPGA with a maximum time delay of fewer than 75 nanoseconds.

The measurements provided below are for typical Vuser values, but the board can also operate between the specified ranges.
Vuser = 5V | Conditions | MINIMUM | TYPICAL | MAXIMUM | UNITS | MODE |
|---|---|---|---|---|---|---|
High Level | RL (1 kohm) | 3 | 3.4 | VDC | Pull Down | |
Iout source max* 80 mA | 2.2 | 2.8 | VDC | |||
Low Level | Iout sink max* 80 mA | 0.2 | VDC | Pull Up |
For more information about the use of Vuser and Vrtn pleaser refer to this article in the OPAL-RT knowledge base : How to power the different DB37 boards for digital outputs.

Low Level | Iout sink max* 100mA | 0.2 | VDC | Pull Up |
*Due to the dual component used in the design, the maximum current value applies to two consecutive channels of the card, and this limitation must be taken into account. For example, for any two consecutive channels, the 100mA limit shared between the two channels can be distributed as follows:
