General Description

The HT1602L is a dot matrix LCD segment

driver LSI implemented in CMOS technology.

The chip contains 40-bit shift register (two 20-

bit shift registers), 40-bit latch (two 20-bit

latches), 40-bit level shifter, 40-bit 4-level

driver and control circuits.

The HT1602L can convert serial data received

from an LCD controller parallel data and then

send them out as LCD driving waveforms to the

LCD panel. The chip is applicable up to 1/16

duty. Furthermore, the bias voltage which de-

termines the LCD driving voltage can be option-

ally supplied from an external source, thus the

chip is suitable for driving various LCD panel.

These special features increase the versatility

of the chip.
