HD66214T

HD66214T (Micro-TAB) (80-Channel Column Driver in Micro-TCP) Description The HD66214T, the column driver for a large liquid crystal graphic display, features as many as 80 LCD outputs powered by 80 internal LCD drive circuits. This device latches 4-bit parallel data sent from an LCD controller, and generates LCD drive signals. In standby mode provided by its internal standby function, only one drive circuit operates, lowering power dissipation. The HD66214, packaged in an 8-mm-wide micro-tape carrier package (micro-TCP), enables a compact LCD system with a narrower frame (peripheral areas for LCD drivers)—about half as large as that os an existing system. The HD66214T is a low power dissipation device powered by 2.7 to 5.5 V suitable for battery-driven portable equipment such as notebook personal computers and palm-top personal computers. Features Duty cycle: 1/64 to 1/240 High voltage — LCD drive: 10 to 28 V High clock speed — 8 MHz max under 5-V operation — 4 MH...
