BGI - Buffered general input
Below is the detailed schematic of the buffered digital inputs.
Schematic:
Notes:
The buffered digital inputs are designed to work with open collector (sinking) or TTL logic outputs. When connecting a TTL output, ensure the logic voltage is 5V.
When a digital input is pulled to ground, current will flow from the internal power supply to ground.
To deactivate the input, a digital input should be left unconnected or switched back to the logic supply. This will stop current from flowing.
