1 Temperature range TMIN to TMAX: –20°C to +85°C.
2 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.
3 Guaranteed by characterization.
4 Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition.
5 See Figure 60.
6 Teletext Port consists of the following:
Teletext Output: TTXREQ
