Oki Electric Industry MSC1208
The MSC1208 is a Bi-CMOS display driver for 1/2-duty vacuum fluorescent display tube. It consists of 58-bit shift registers, latch circuits, a 10-bit digital dimming circuit, 4 ¥ 4 switch matrix, and a keyscan circuit for 2-channel, 3-contact rotary switch. With these features, the MSC1208 not only can display frequencies for audio systems used in automobile applications and various information, but also can accept keyboard entry.| Part No. | MSC1208 |

GENERAL DESCRIPTION
Thus the front panel functions can be carried out only by this IC. Since the MSC1208 has the data parity check function and the self-check functions, inspection at shipment and failure detection can easily be performed. In addition, since the MSC1208 uses serial interfacing, only two signal lines, DATA ENABLE and DATA I/O, are used for connection with a microcontroller.FEATURES
