TB2104F

VFD Driver TOSHIBA Bi−CMOS Integrated Circuit Silicon Monolithic TB2104F TB2104F 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). Weight: 0.7g (typ.) · In serial data mode, multiple drivers can be cascaded to expand the handling capacity in 20bit increments.
