Temperature range T
TTL input values are 0 V to 2.8 V, with input rise/fall times −3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and outputs.
Analog output load –10 pF.
Guaranteed by characterization.
Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition.
See Figure 60.
Teletext Port consists of the following:
