MSC1164

E2C0011-27-Y4 ¡ Semiconductor MSC1164 ¡ Semiconductor 20-Bit Grid/Anode Driver This version: Nov. 1997 MSC1164 Previous version: Jul. 1996 GENERAL DESCRIPTION The MSC1164 is a monolithic IC using the Bi-CMOS process technology for hybridizing CMOS and bipolar transistors on the same chip. The logic portion such as the input stage, shift register and latch is fabricated by CMOS and the output driver requiring a high withstand voltage is fabricated by bipolar transistors. Since a 32-pin plastic SSOP package is used, the display unit size can be reduced. FEATURES The MSC1164 is designed as a VFD grid/anode driver with emitter-follower force output with 20-bit active pull-down and built-in 20-bit shift register and latch. Logic Supply Voltage (VCC) : 5V : 65V Driver Supply Voltage (VHV) Driver Output Current IOHVH1 :–40mA (Only one driver output: "H") IOHVH2 :–2mA (All driver outputs: "H") IOHVL :2mA 20-bit output (with latch circuit) 20-bit shift register Clock frequency : 4MHz Package options: 32-pin plastic SSOP (SSOP32-P-430-1.00-K) (Product name: MSC1164GS-K) 30-pin plastic shrink DIP (SDIP30-P-400-1.78) (Product name: MSC1164SS) 1/13 ¡ Semiconductor MSC1164 BLOCK DIAGRAM CLK DIN LS CHG CL V CC V HV D HVO1 R-1 1 1 HVO2 R-2 2 2 20-Bit Shift Register 20-Bit Latch HVO20 R-20 Q 20 20 DOUT GND 2/13 ¡ Semiconductor MSC1164 INPUT AND OUTPUT CONFIGURATION Schematic Diagrams of Logic Portion Input and Output Circuits Input Pin VCC VCC INPUT GND GND ...
