Note:
Power-up Reset
The ATF16LV8C’s registers are designed to reset during
power-up. At a point delayed slightly from V
V
the registered output state will always be high on power-up.
This feature is critical for state machine initialization.
However, due to the asynchronous nature of reset and the
uncertainty of how V

Similar devices are tested with slightly different loads.
These load differences may affect output signals’ delay
and slew rate. Atmel devices are tested with sufficient
margins to meet compatible devices.
