NOTES
1R, G, and B signals are inputted via an external ac coupling capacitor.
2Except during dc restore period (back porch clamp).
3All outputs measured at a 75 Ω reverse-terminated load; ac voltages at the IC output pins are twice those specified here.
4Ratio of chroma amplitude to burst amplitude, difference from ideal.
5Difference between ideal color-bar phases and the actual values.
6Driving the logic inputs with VOH < 4 V will increase static supply current approximately 150 µA per input.
Specifications are subject to change without notice.
