Product Overview

The MAX6934AQH+D is a 32 outputs, 76V, serial-interfaced VFD tube driver in 44 pin PLCC package. The vacuum-fluorescent display (VFD) tube driver interfaces a VFD tube to a microcontroller or a VFD controller such as the MAX6850-MAX6853. It is suitable for driving telecom relays. Data is input using standard 4-wire serial interface (CLOCK, DATA, LOAD, BLANK) compatible with other VFD drivers and controllers. For easy display control, the active-high BLANK input forces all driver outputs low, turning the display off and automatically puts the IC into shutdown mode. Display intensity may also be controlled by directly pulse-width modulating the BLANK input. It has a serial interface data output DOUT allowing any number of devices to be cascaded on the same serial interface. It also has a negative supply voltage input VSS allowing the drivers output swing to be made bipolar to simplify filament biasing in many applications.
  • Logic supply range from 3V to 5.5V
  • Grid/anode supply range from 8V to 76V
  • Filament bias supply range from-11V to 0V
  • Push-pull CMOS high-voltage outputs
  • Outputs can source 40mA, sink 4mA continuously
  • Outputs can source 75mA repetitive pulses
  • Outputs can be paralleled for higher current drive
  • Any output can be used as a grid or an anode driver
  • BLANK input simplifies PWM intensity control
  • Operating temperature range from -40°C to 125°C
