Maxim Integrated (MAX6934AQH+D) Display Driver, Vacuum Fluorescent

Product OverviewThe MAX6934AQH+D from Maxim Integrated Products is a 32 outputs, 76V,serial-interfaced VFD tube driver in 44 pin PLCC package. The vacuum-fluorescentdisplay (VFD) tube driver interfaces a VFD tube to a microcontroller or a VFDcontroller such as the MAX6850-MAX6853. It is suitable for driving telecomrelays. Data is input using standard 4-wire serial interface (CLOCK, DATA, LOAD,BLANK) compatible with other VFD drivers and controllers. For easy displaycontrol, the active-high BLANK input forces all driver outputs low, turning thedisplay off and automatically puts the IC into shutdown mode. Display intensitymay also be controlled by directly pulse-width modulating the BLANK input. Ithas a serial interface data output DOUT allowing any number of devices to becascaded on the same serial interface. It also has a negative supply voltageinput VSS allowing the drivers output swing to be made bipolar to simplifyfilament biasing in many applications.Logic supply range from 3V to 5.5VGrid/anode supply range from 8V to 76VFilament bias supply range from-11V to 0VPush-pull CMOS high-voltage outputsOutputs can source 40mA, sink 4mA continuouslyOutputs can source 75mA repetitive pulsesOutputs can be paralleled for higher current driveAny output can be used as a grid or an anode driverBLANK input simplifies PWM intensity controlOperating temperature range from -40°C to 125°CAvionics; Gaming Machines; Industrial Control; Industrial Weighing;Instrumentation; Security; Telecom; VFD Modules; White GoodsApplicationsAvionics, Industrial, Security, Communications & Networking, ConsumerElectronicsProduct InformationNo. of Digits: -No. of Segments: -Driver Case Style: PLCCNo. of Pins: 44PinsSupply Voltage Min: 3VSupply Voltage Max: 5.5VInterface Type: SerialOperating Temperature Min: -40°COperating Temperature Max: 125°CProduct Range: -MSL: MSL 3 - 168 hours
