40-DOT SEGMENT DRIVER

The MSM5259 is a dot matrix LCD segment driver which is fabricated using low power CMOS metal Gate technology. This LSI consists of 40-bit Shift register 40-bit latch and 40-bit 4-level driver. It converts serial data, which is received from an LCD Controller LSI, to parallel data and outputs LCD driving waveforms to LCD Expansion of the Display CAN be easily made according to the number and structure of characters. Since the 40-bit Shift register of this device consists of two 20-bit Shift registers it is possible to allot bits efficiently according to the number of characters. The MSM5259 CAN drive a variety of LCD panels because the bias voltage, which determines the LCD driving voltage, CAN be optionally supplied from the external source. For static operation only, the device is available with a power supply voltage of 2.5V or more.
