DUTY

GRID1-16

I

Duty control signal input pin.

Setting this pin to "L" makes all driver outputs go "L", so this pin can be used for brightness

control.

4- to 16-line decoder input pins.

The input 4-bit binary signals are converted into hexadecimal signals, then output through

driver output pins.

I

O

High withstand voltage driver output pins for driving fluorescent display tube.

These pins can directly be connected to the grid of fluorescent display tude without

pull-down resistor.

Power supply pin for the fluorescent display tube driver circuit.

Logic power supply pin.

Ground pin.
