Product Summary

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

Parametrics

TB2104F absolute maximum ratings: (1)supply voltage: -0.3 to 7.0V; (2)Input voltage: -0.3 to VDD+0.3V; (3)Driver voltage: VDD~60V; (4)Driver current: 50mA; (5)Power dissipation: 800mW; (6)Operating temperature: -40 to 85℃; (7)Storage temperature: -55 to 150℃.

Features

TB2104F features: (1)Incorporates a shift register, latch, and driver capable of handling 20bits of data.; (2)The output driver comes with an active pull down, so it can function as a VFD grid, anode driver.; (3)Three serial data lines are used to input display data; (4)The data reciever section can also accept general purpose serial data and T-BUS; (5)In serial data mode, multiple drivers can be cascaded to expand the handling capacity in 20bit increments.
