12-Output, 76V, Serial-Interfaced

VFD Tube Driver

General Description

Features

ꢀ 5MHz Industry-Standard 4-Wire Serial Interface

ꢀ 3V to 5.5V Logic Supply Range

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.

ꢀ 8V to 76V Grid/Anode Supply Range

ꢀ Push-Pull CMOS High-Voltage Outputs

ꢀ Outputs can Source 40mA, Sink 4mA

Data is inputted using an industry-standard 4-wire serial

interface (CLOCK, DATA, LOAD, BLANK) for compatibili-

ty with both industry-standard drivers and Maxim’s VFD

controllers.

Continuously

ꢀ Outputs can Source 75mA Repetitive Pulses

ꢀ Outputs can be Paralleled for Higher Current

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.

Drive

ꢀ Any Output can be Used as a Grid or an Anode

Driver

ꢀ Blank Input Simplifies PWM Intensity Control

ꢀ Small 20-Pin SO Package

The MAX6920 has a serial interface data output pin,

DOUT, allowing any number of devices to be cascaded

on the same serial interface.

ꢀ -40°C to +125°C Temperature Range

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).
