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.
