UPD16312 1/4- to 1/11-DUTY FIP (VFD) CONTROLLER/DRIVER

Input serial data at rising edge of shift clock, starting from the low order bit. Output serial data at the falling edge of the shift clock, starting from low order bit. This is N-ch open-drain output pin. Initializes serial interface at the rising or falling edge of the DOUT Data output 5 STB .

DATA SHEET MOS INTEGRATED CIRCUIT PD16312 1/4- to 1/11-DUTY FIPTM (VFD) CONTROLLER/DRIVER The PD16312 is a FIP (fluorescent Indicator Panel, or 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 drive lines, a display memory, a control circuit, and a key scan circuit. Serial data is input to the PD16312 through a three-line serial interface. This FIP controller/driver .
