STTS424
Note:
Figure 9.
Table 11.
Systems that use the active high mode for event output must be wired pont-to-point between
the STTS424 and the sensing controller. Wire-OR configurations should not be used with
active high EVENT since any device pulling the event output signal low will mask the other
devices on the bus. Also note that the normal state of EVENT in active high mode is a ‘0’
which will constantly draw power through the pull-up resistor.
