General Description

The HT1608 is an LCD driver LSI with 40

output channels using the CMOS technology. It

is equipped with two sets of 20-bit bidirectional

shift registers, 20-bit data latches, 20-bit LCD

drivers, and logic control circuits. The LSI can

convert serial data received from an LCD con-

troller into parallel data and supply LCD driv-

ing waveforms to the LCD panel.

The HT1608 is designed for general purpose

LCD drivers. It can drive both static and dy-

namic drive LCDs. The LSI can be applied to

either a common driver or a segment driver.
