TB2104F Description
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.
TB2104F Key Features
- Incorporates a shift register, latch, and driver capable of handling 20 bits of data
- The output driver es 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
- Chip select / address setting inputs -When using in serial mode, keep AD1 and AD2 “open”. -In other settings than “open”
- Serial data input terminals -Inputs display data through the DIN terminal
- Lamp test input terminal and data output terminal -In serial mode (AD1 = AD2 = open), this terminal serves as
- Driver off (blanking) input terminal -All the driver outputs are fixed at “L” level when “L”
- Power supply and GND terminals
