Description

R, G and B output DC voltage setting.

Connect a 0.01µF capacitor between

this pin and GND2.

When used with a signal output DC

voltage of other than VCC2/2, apply

voltage of 5.2 to 6.5V from an external

source.

Analog 3V power supply.

GND1

External digital signal inputs.

There are two threshold values:

25µA

Vth1 (approximately 1.0V) and

Vth2 (approximately 2.0V).

300

When one of the RGB signals exceeds

Vth1, all of the RGB outputs go to black

level; when an input exceeds Vth2, only

50k 0.7V the corresponding output goes to white

level.

Connect these pins to GND when not

used.

2µA

TG block system reset.

300

The system is reset by connecting this

pin to GND.

Normally connect a capacitor between

this pin and GND.

(Threshold value = 2.0V)
