The min/max values are typical over 4.75 V to 5.25 V range. 2 Ambient temperature range TMIN to TMAX: −40°C to +85°C. The die temperature, TJ, must always be kept below 110°C. 3 TTL input values are 0 V to 3 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. 4 Guaranteed by characterization 5 Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition. 6 Pixel port consists of the following: Pixel inputs: P15–P0 Pixel controls: HSYNC, FIELD/VSYNC, BLANK Clock input: CLOCK 7 Teletext port consists of the following: Teletext output: TTXREQ Teletext input: TTX |
