Oki Electric Industry MSC1164
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.GENERAL DESCRIPTION
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
