General Description
The HT1608L is an LCD driver LSI with 40
output channels using 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 HT1608 can convert serial data received

from an LCD controller into parallel data and
send out LCD driving waveforms to the LCD
panel. The HT1608L is designed for general
purpose LCD drivers. It can drive both static
and dynamic drive LCDs. The chip can be ap-
plied to a common driver or a segment driver.
