The MAX6920 is a 12-output, 76V, vacuum fluorescent display (VFD) tube driver that interfaces a multiplexed VFD tube to a VFD controller such as the MAX6850-MAX6853 or to a microcontroller. The MAX6920 is also ideal for driving either static VFD tubes or telecom relays. Data is inputted using an industry-standard 4-wire serial interface (CLOCK, DATA, LOAD, BLANK) for compatibility with both industry-standard drivers and Maxim's VFD controllers. For easy display control, the active-high BLANK input forces all driver outputs low, turning the display off, and automatically puts the MAX6920 into shutdown mode. Display intensity may also be controlled by pulse-width modulating the BLANK input. The MAX6920 has a serial interface data output pin, DOUT, allowing any number of devices to be cascaded on the same serial interface. The MAX6920 is available in a 20-pin SO package. Maxim also offers VFD drivers with either 20 (MAX6921/MAX6931) or 32 outputs (MAX6922 and MAX6932).
