The TLV903xL1
push-pull output is
High-Z (neither sinking or sourcing current) during the POR period. Following the POR period, the latch is armed and latches
high upon the first low-to-high output transition.
The following is a summary of the latch operation.
- Output is Hi-Z during the POR period at first power-up.
- During POR period, input transition is ignored.
- Following the POR period, comparator is armed and monitors inputs.
- IN+ now higher than IN-, setting output high and latching high.
- IN- greater than IN+, but output still remains high (latched).
- CLR falling edge resets latch for next transition. IN- > IN+, output remains low and armed for next input transition.
- IN+ > IN-, setting output high and latching again. Output remains latched even when IN- > IN+.
