Description
4- to 16-line decoder input pins
The input 4-bit binary signals are converted into hexadecimal signals, then output
through driver output pins.
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.
High withstand voltage driver output pins for driving fluorescent display tube
These pins can be connected directly to the grid of fluorescent display tube.
No pull-down resistor is required.
Power supply pin for the fluorescent display tube driver circuit
Logic power supply pin
Ground pin
