Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.
October 1, 2008

20-Bit Grid/Anode Driver
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.
