E2C0021-27-Y3 ¡ Semiconductor ¡ Semiconductor MSC1212-01 48-Bit Grid/Anode Driver This version: Nov. 1997 MSC1212-01 Previous version: Jul. 1996 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) Driver supply voltage (VDISP) Operating temperature range Driver output current : : : : 4.5 to 5.5 V 8 to 18 V –40 to +105°C IO2-1 = –6 mA (for only one driver on state) IO2-2 = –50 mA (total current for all drivers on state) IO2-3 = 0.2 mA 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) 1/11 ¡ Semiconductor MSC1212-01 BLOCK DIAGRAM VDISP VCC CL CHG VCC LS DIN CLK C SI I1 48-BIT LATCH I48 O48 HVO48 DOUT L O1 HVO 1 PO1 48-BIT S/R L-GND D-GND PO48 SO 2/11 ¡ Semiconductor PIN CONFIGURATION (TOP VIEW) ,  HVO 17 HVO 16 HVO 15 HVO 14 HVO 13 HVO 12 HVO 11 HVO 10 HVO 9 HVO 8 HVO 7 HVO 6 HVO 5 HVO 4 HVO 3 HVO 2 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 MSC1212-01 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 NC HVO 18 HVO 19 HVO 20 HVO 21 HVO 22 HVO 23 HVO 24 HVO 25 HVO 26 HVO 27 HVO 28 HVO 29 HVO 30 HVO 31 NC 48 47 46 45 44 43 42 41...
