MSC1212-01
48-Bit Grid/Anode Driver
GENERAL DESCRIPTION
The MSC1212-01 is a driver IC for VFD implemented in BiCMOS technology.
The circuit consists of a 48-bit shift register and a 48-bit latch; they control display data, which
is output from the display drivers.
Since a 64-pin plastic QFP package is used, the display unit size can be reduced.
FEATURES
• Logic supply voltage (VCC) : 4.5 to 5.5 V
• Driver supply voltage (V
• Operating temperature range : –40 to +105°C
• Driver output current : I
• Built-in 48-bit output Driver (with latch)
• Built-in 48-bit shift register
• Clock frequency : 0.5 MHz
• Package:
64-pin plastic QFP (QFP64-P-1414-0.80-BK) (Product name: MSC1212-01GS-BK)
) : 8 to 18 V
