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.
