Input Electrical Specifications

All VA61 inputs are single-ended, with the following specification:
Signal state
Low (Inactive)
High (Active)
Turn ON current

Output Electrical Specifications

All VA61 outputs are single-ended, open collector, current sinking (NPN), with the following
specification:

Output Voltage
Output Sink Current
Short Circuit Protection
NOTE
The NPN outputs are Open Collector. A pull-up resistor is needed to test the out-
puts.
