HD66224T (Dot Matrix Liquid Crystal Graphic Display Column Driver with 80-Channel Outputs) Description The HD66224T is a column driver for dot matrix liquid crystal graphic display system. It has 80 liquid crystal drive circuits and can drive large LCDs. The column driver latches parallel data for display (4/8 bit parallel) from the controller, then generates a drive signal and selects the proper LCD drive voltage. A built-in standby function that allows all internal drivers except one to be placed in standby mode (IST) lowers device power consumption. The column driver package is a 7.5mm wide ultra-small tape carrier package (TCP), allowing designs using half the frame area of conventional displays. The column driver can be used in a wide range of battery-powered designs because its logic power supply can operate with an input voltage ranging from 2.5 to 5.5 V. Features Display duty cycle: 1/64 to 1/240 Number of liquid crystal drive circuits: 80 Parallel data transfer: ...
