Test measurement levels for the PI6C3991 are TTL levels (1.5V to 1.5V). Test conditions assume signal transition times of 2ns or less
and output loading as shown in the AC Test Loads and Waveforms unless otherwise specified.
Guaranteed by statistical correlation. Tested initially and after any design or process changes that may affect these parameters.
SKEW is defined as the time between the earliest and the latest output transition among all outputs for which the same t
