Specifications subject to change without notice.
The max/min specifications are guaranteed over this range. The max/min values are typical over 3.0 V to 3.6 V.
Temperature range T
TTL input values are 0 to 3 volts, with input rise/fall times ≤ 3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and
Guaranteed by characterization.
Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition.
Pixel Port consists of the following:
Teletext Port consists of the following:
