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. How-
ever, 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
