HD44103 Datasheet | Hitachi Semiconductor

(Dot Matrix Liquid Crystal Graphic Display 20-Channel mon Driver) Description The HD44103 is a mon signal driver for dot matrix liquid crystal 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 mon signals of the liquid crystal according to the display duty. It can select 5 types of display duty ratio: 1/8, 1/12, 1/16, 1/24, and 1/32. 20 driver output lines are provided, and the impedance is low (500 Ω max.) to enable a large screen to be driven. Features - Dot matrix liquid crystal graphic display mon driver incorporating the timing generation circuit - Internal oscillator (oscillation frequency can be selected by attaching an oscillation resistor and an oscillation capacity) - Generates display timing signals - 20-bit bidirectional shift register for generating mon signals - 20 liquid...
