Static driver
When the HT1609L is used as a static driver,
data is transferred on the falling edge of CLK2
and latched on the falling edge of CLK1. The
frequency of CLK1 becomes the frame fre-
quency of the LCD driver. The frequency of ALT
has to be twice the frequency of CLK1. ALT has
to be synchronized on the falling edge of CLK1.
The power supply for the LCD driver is used by
shortening V1, V4 or V2, V3. The application
circuit connections are shown below:
