Part Description: MAX6922 DS


Part Details:

19-3224; Rev 2; 3/07 27-, 28-, and 32-Output, 76V, Serial-Interfaced VFD Tube Drivers MAX6922/MAX6932/MAX6933/MAX6934 General Description Features The MAX6922/MAX6932/MAX6933/MAX6934 multi-out- 5MHz Industry-Standard 4-Wire Serial Interface put, 76V, vacuum-fluorescent display (VFD) tube drivers 3V to 5.5V Logic Supply Range that interface a VFD tube to a microcontroller or a VFD 8V to 76V Grid/Anode Supply Range controller, such as the MAX6850­MAX6853. TheMAX6922/MAX6934 have 32 outputs, while the MAX6932 -11V to 0V Filament Bias Supply has 27 outputs, and the MAX6933 has 28 outputs. All (MAX6932/MAX6933/MAX6934 Only) devices are also suitable for driving telecom relays. Push-Pull CMOS High-Voltage Outputs Data is input using standard 4-wire serial interface Outputs Can Source 40mA, Sink 4mA (CLOCK, DATA, LOAD, BLANK) compatible with other Continuously VFD drivers and controllers. Outputs Can Source 75mA Repetitive Pulses For easy display control, the active-high BLANK input Outputs Can Be Paralleled for Higher Current Drive forces all driver outputs low, turning the display off, and Any Output Can Be Used as a Grid or an Anode automatically puts the IC into shutdown mode. Display Driver intensity may also be controlled by directly pulse-width modulating the BLANK input. BLANK Input Simplifies PWM Intensity Control -40°C to +125°C Temperature Range as Standard The MAX6922/MAX6932/MAX6934 have a serial inter-face data output, DOUT, allowing any number ofdevices to be cascaded on the same serial interface. Ordering Information The MAX6932/MAX6933/MAX6934 have a negativesupply voltage input, V PIN- PKG SS, allowing the drivers output PART TEMP RANGE swing to be made bipolar to simplify filament biasing in PACKAGE CODE many applications. MAX6922AQH -40°C to +125°C 44 PLCC Q44-1 The MAX6922 is available in a 44-pin PLCC package, MAX6932AAX -40°C to +125°C 36 SSOP
