Input characteristics
:
•
The falling edge is detected as the external drive pulses the line low, and the internal drive latches the
line low

Output characteristics
:
•
The physical line state does not change until all drives (internal and external) release the line.
Synchronous trigger mode
The synchronous trigger mode is a combination of SynchronousA and SynchronousM trigger modes.
The SynchronousA and SynchronousM trigger modes provide additional flexibility.
