Product Summary

The PT6554LQ is a high performance Liquid Crystal Display (LCD) Driver IC utilizing CMOS technology specially designed with Key Input function. It can drive up to a maximum of 164 segments and control up to 4 general purpose output ports. It includes a Key Scan Circuit that can support up to 30 key inputs and provides On-Chip Voltage Detection Type Reset Circuit which prevents incorrect display. Display Data can be directly displayed without using any decoder. The PT6554LQ also supports both 1/4 duty-1/2 bias and 1/4 duty-1/3 bias drive techniques. Pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
