ML9261A
60-Bit Vacuum Fluorescent Display Tube Grid/Anode Driver
1/16
GENERAL DESCRIPTION
The ML9261A is a monolithic IC designed for directly driving the grid and anode of the vacuum fluorescent
display (VFD) tube. The device contains a 60-bit shift register, a 60-bit register circuit, and 60 VFD tube driving
circuits on a single chip.
Display data is serially stored in the shift register at the rising edge of a clock pulse.
Setting the
CL pin low allows all the VFD tube driving circuits to be driven low, which makes it possible to set the
display blanking.
Also, setting both of the
CL and CHG pins high allows all the VFD tube driving circuits to be driven high, which
provides the easy testing of all lights after final assembly of a VFD tube panel.
FEATURES
• Logic Supply Voltage (VDD)
: +3.3 V
± 10% or +5.0 V ± 10%
• Driver Supply Voltage (VDISP)
: +20 to +60 V
• Driver Output Current
IOHVH1 (Only one driver output: “H”)
: –40 mA (VDISP = 40 V)
IOHVH2 (All the driver outputs: “H”)
: –120 mA (VDISP = 40 V)
IOHVL
: 1 mA
• Directly connected to VFD tube by using push-pull output (Pull-down resistors are not needed)
• Data Transfer Speed
: 4 MHz
• Package: 70-pin plastic SSOP (SSOP70-P-500-0.80-K)
: ML9261AMB
