PT6608 is a 64 -channel segment driver for dot matrix liquid crystal graphic display system. It utilizes CMOS Technology and provides display RAM, 64-bit data latch, 64 bit drivers and decoder logics. It features the internal display RAM used as storage for the display data which are transferred from an 8-bit microcontroller. It generates the dot matrix liquid crystal driving signals corresponding to the given stored data. Paired with PT6607 (Common Driver IC), PT6608s pin assignments and application circuit are optimized for easier PCB Layout and cost saving advantages.
