INPUT/OUTPUT EQUIVALENT SCHEMATICS
Circuitry within the GAL16V8 provides a reset signal to all reg-
isters during power-up. All internal registers will have their Q
outputs set low after a specified time (
tpr, 1μs MAX). As a result,
the state on the registered output pins (if they are enabled) will
always be high on power-up, regardless of the programmed
polarity of the output pins. This feature can greatly simplify state
machine design by providing a known state on power-up. Be-
cause of the asynchronous nature of system power-up, some

conditions must be met to provide a valid power-up reset of the
device. First, the VCC rise must be monotonic. Second, the clock
input must be at static TTL level as shown in the diagram during
power up. The registers will reset within a maximum of
tpr time.
As in normal system operation, avoid clocking the device until all
input and feedback path setup times have been met. The clock
must also meet the minimum pulse width requirements.
