产品概述

The MAX6921AUI+ is a 20 output, 76V, serial interfaced VFD tube driver in 28 pin TSSOP package. It is a 20 output, 76V, vacuum fluorescent display (VFD) tube driver that interface a multiplexed VFD tube to a VFD controller such as the MAX6850 and MAX6853 or to a microcontroller. The MAX6921 also ideal for driving static VFD tubes or telecom relays. Data is input using an industry standard 4 wire serial interface (CLOCK, DATA, LOAD, BLANK) compatible with either Maxim's or industry standard VFD driver and controller. For easy display control, the active high BLANK input forces all driver outputs low, turning the display off and automatically puts the MAX6921 into shutdown mode. Display intensity can also be controlled by directly pulse width modulating the BLANK input. The MAX6921 has a serial interface data output DOUT allowing any number of devices to be cascaded on the same serial interface.
  • Supply voltage range is 3V to 5.5V
  • Operating temperature range from -40°C to 125°C
  • 5MHz industry standard 4 wire serial interface
  • Grid/anode supply range from 8V to 76V
  • 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
