VFD Driver/Controller IC
PT6305
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.

Notes:
1. 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.

Notes:
1. All dimensioning and tolerancing dimension conform to ASME Y14.5M-19942.
2. Dimensions “D1” and “E1” do not include mold protrusion, allowable protrusion is 0.25 mm per side.
3. Regardless of the relative size of the upper and lower body sections, dimensions “D1” and “E1” are
determined at the largest feature of the body exclusive of mold flash and gate burrs but including
any mismatch between the upper and lower sections of the molded body.
4. All dimensions are in millimeters
5. Dimension “b” do not include dambar protrusion. The dambar protrusion(s) shall not cause the lead
width to exceed “B” maximum by more than 0.08 mm. Dambar cannot be located on the lower
radius or the lead foot.
6. Refer to JEDEC MS-022 Variation GC-1
