Description

General part information

MAX6922 Series

The MAX6922/MAX6932/MAX6933/MAX6934 multi-output, 76V, vacuum-fluorescent display (VFD) tube drivers that interface a VFD tube to a microcontroller or a VFD controller, such as the MAX6850–MAX6853. The MAX6922/MAX6934 have 32 outputs, while the MAX6932 has 27 outputs, and the MAX6933 has 28 outputs. All devices are also 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.The MAX6922/MAX6932/MAX6934 have a serial interface data output, DOUT, allowing any number of devices to be cascaded on the same serial interface.The MAX6932/MAX6933/MAX6934 have a negative supply voltage input, VSS, allowing the drivers' output swing to be made bipolar to simplify filament biasing in many applications.The MAX6922 is available in a 44-pin PLCC package, the MAX6932 and MAX6933 are available in 36-pin SSOP packages, and the MAX6934 is available in 44-pin PLCC and TQFN packages.Maxim also offers a 12-output VFD driver (MAX6920) and 20-output VFD drivers (MAX6921/MAX6931).ApplicationsAvionicsGaming MachinesIndustrial ControlIndustrial WeighingInstrumentationSecurityTelecomVFD ModulesWhite Goods
