PT6574

• CMOS Technology
• RC Oscillator Circuit
• Up to 264 Segments
• Supports 1/4 Duty, 1/2 Bias Drive or 1/4 Duty 1/3 Bias Drive Techniques (Serial Data Control)
• RC Oscillation Circuit

PT6574 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.
