GENERAL DESCRIPTION

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.
