The OP5367 features a 32 channel digital input/output board. The output channels operating at 5 V (CMOS/TTL) or 3.3 V (LVTTL) and the input channels are high impedance with programmable high and low thresholds.

Main Features

• The 32 input channels are grouped into four banks of 8 channels, each with independent thresholds per bank.

• Digital In programmable threshold 0-50V.

• The 32 output channels are configurable for either 5 V ±10% (CMOS/TTL Logic ) or 3.3 V (LVTTL).

• Digital Out TTL, max output current: 32 mA/ch or 800 mA total combined

• Low latency < 20 ns, High resolution of 10 ns with 100 MHz FPGA.

• Galvanically isolation to real environment signals provides protection to the simulator from damaging voltages.

Ouptut Voltage Selection

It is possible to select the output voltage of all channels for +3.3V (LVTTL) or +5.0V (TTL) operation via a dip switch installed on the OP5367.

See the location of the dip switch in the picture below:

Typical Use Cases

The card is ideal for interfacing with devices operating at low voltage.
