MSC1201-XX Datasheet 60-bit Vfd Tube Driver

Manufacturer: OKI Electric

Overview: E2C0017-27-Y2 ¡ Semiconductor MSC1201-xx ¡ Semiconductor This version:MSC1201-xx Nov. 1997 Previous version: Jul. 1996 www.DataSheet4U.

General Description

The MSC1201-xx is a 1/2 duty vacuum fluorescent display tube driver implemented in Bi-CMOS technology.

This LSI consists of 64-bit shift registers, 64 latches, PWM conversion circuit, a digital dimming circuit, 30-segment driver and 2-grid driver.

As the MSC1201-xx has both a digital dimming circuit and a PWM conversion circuit which converts PWM signal for lamp dimming control to PWM signal for VFD tube dimming control, the dimming control can be realized without any external circuit.
