Channel B Video Input. Use channel B for the green (G) video signal. AC-couple INB with a series 0.1µF
capacitor.
Channel C Video Input. Use channel C for the blue (B) video signal. AC-couple INC with a series 0.1µF
capacitor.
Disable Logic Input. Connect DISABLE to GND for normal operation. Connect DISABLE to V
buffer outputs and put them in a high-impedance state.
External Sync Input. Use TTL logic levels. A logic high enables the DC restore loop and clamps the output
voltages to + 1.5V (typ).
Ground
No Connection. Make no connection to these pins.
Channel C Buffer Output. This output can be either AC- or DC-coupled.
Channel B Buffer Output. This output can be either AC- or DC-coupled.
Channel A Buffer Output. This output can be either AC- or DC-coupled.
