Notes: (1). Maximum load of 20 pf.
(2). At Fmax. ICC (typ) at VCC = 5.0 V. ICC (max) at VCC = 5.25 V. OSC/PCLOCK = 2, CLOCK/HSYNC
100.
3. Test conditions (unless otherwise specified):"Recommended Operating Conditions." TTL input values are
0–3 V, with input rise/fall times
4 ns, measured between the 10% and 90% points. Timing reference points
at 50% for inputs and outputs. CLOCK, HSYNC, CLAMP, ZERO, VSYNC*, FIELD, CAPTURE, and CSYNC*
output load
50 pF, D0–D7 output load
130 pF. Typical values are based on nominal temperature, i.e., room
temperature, and nominal voltage, i.e., 5 V.
