VFD Driver

The TB2104F is a VFD (fluorescent display tube) driver IC implemented by the Bi−CMOS process. The logic section is configured with CMOS transistors, and the high voltage tolerant output driver section is configured with bipolar transistors.

Features

• Incorporates a shift register, latch, and driver capable of handling 20 bits of data.

• The output driver comes with an active pull−down, so it can function as a VFD grid, anode driver.

• Three serial data lines are used to input display data.

• The data receiver section can also accept general−purpose serial data and T−BUS (TOSHIBA semiconductor bus).

• In serial data mode, multiple drivers can be cascaded to expand the handling capacity in 20bit increments.
