HD44105 Dot Matrix Liquid Crystal Graphic Display Common Driver

The HD44105 is a common signal driver for LCD dot matrix graphic display systems. It generates the timing signals required for display with its internal oscillator and supplies them to the column driver (HD44102) to control display, also automatically scanning the common signals of the liquid crysta.

HD44105 Features

* Dot matrix graphic display common driver including the timing generation circuit

* Internal oscillator (oscillation frequency is selectable by attaching an oscillation resistor and an oscillation capacitor)

* Generates display timing signals

* 32-bit bidirectional s
