DESCRIPTION

PT6305 is a 48-Bit High Voltage Display Driver utilizing CMOS technology specially designed for VFD display panels. It provides a 48-bit shift register, a 48-bit latch and a high-voltage CMOS driver. The logic circuit operates on a 5 volt power supply (CMOS level input) making it possible for the PT6305 to be used in conjunction with a microcomputer. The driver block consists of an 80 volt, 50mA (max.) high voltage output buffer. Pin assignments and application circuits are optimized for easy PCB layout and cost saving benefits.

FEATURES

  • CMOS technology
  • Low power consumption
  • 48-bit shift registers
  • Data controlled via external transfer clock and latch
  • High speed data transfer
  • Wide operating temperature range: -40 to +85 Ċ
  • High voltage output (70V, 40mA)
  • Polarities of all drivers may be inverted by using PCB pin
  • Available in 100-pins QFP package APPLICATION
  • Microcomputer peripherals

Use all the Power Supply Pins: VDD1, VDD2, VSS1, VSS2 (Make sure that VSS1 and VSS2 Pins have the same Voltage Level.) 2. Power must be supplied to VDD1, Logic Inputs and VDD2 so that the device may be protected from any harm caused by latch up. Power must be turned off in a reversed manner. Power ON. OFF sequences must be observed at all times, even during the transition period.
