TOSHIBA Bi−CMOS Integrated Circuit Silicon Monolithic

TB2104F

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.
