TP6317
1/4 TO 1/11-DUTY VFD CONTROLLER/DRIVER
General Description
The TP6317 is a VFD (Vacuum Fluorescent Display)
controller/driver that is driven on a 1/4 to 1/11-duty
factor. It consists of 11 segment output lines, 6 grid
output lines, 5 segment/grid output drivelines, a
display memory, a control circuit, stand-by control,
and a key scan circuit. Serial data is input to TP6317
through a three-line serial interface. This VFD
controller/driver is ideal as a peripheral device for
front panel control of green DVD/VCD feature.
