The TLV903xL2 push-pull output latches high (sourcing current) during the POR period. Following the POR period, the output is latched high and must be cleared by a high-to-low transition on the CLR pin.
The following is a summary of the latch operation.
- Output is high during the POR period following first power-on.
- Input transition is ignored during POR period.
- Following the POR period, the OUT latches high.
- IN+ passes IN-, but transition is ignored during latch.
- CLR falling edge resets and arms latch awaiting next transition.
- IN+ > IN-, so OUT goes high and latches.
- IN- > IN+, but OUT remains latched high.
- CLR falling edge resets and arms latch for next transition.
- IN+ crosses IN-, output goes high and latches again.
- Output remains latched high even when IN- > IN+.
