Description

PT6574LQ is a 1/4 -duty general purpose LCD Driver IC utilizing CMOS Technology. It can drive up to 264 segments and control up to 8 general purpose output ports. The LCD drive block voltage range is from 2.7V to 6.0V and is independent of the logic block power supply voltage. Under a serial data interface, PT6574 can support 1/4 duty, 1/2 bias or 1/4 duty, 1/3 bias drive techniques. Display data is displayed directly without the need for a decoder circuit. Pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
