MAX6921, MAX6931 20-Output, 76V, Serial-Interfaced VFD Tube Drivers

The MAX6921 MAX6931 are 20-output, 76V, vacuum-fluorescent Display (VFD) tube drivers that Interface a multiplexed VFD tube to a VFD controller, such as the MAX6850-MAX6853, or to a Microcontroller The MAX6921 MAX6931 are 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), compatibile 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 MAX6931 into shutdown mode. Display intensity may 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
The MAX6931 has a negative supply voltage input, VSS, allowing the drivers' output swing to be made bipolar to simplify filament biasing in many applications.
The MAX6921 is available in 28-pin TSSOP, SO, and PLCC packages. The MAX6931 is available in a 28-pin TSSOP package.
Maxim also offers 12-output VFD drivers MAX6920 and 32-output VFD drivers MAX6922 MAX6932 .
