Holtek Semiconductor HT1602
The HT1602 is a dot matrix LCD segment driver LSI implemented in CMOS technology. It is equipped with a 40-bit shift register (two 20-bit shift registers), a 40-bit latch (two 20-bit latches), a 40-bit level shifter, a 40-bit 4-level driver, and control circuits. The HT1602 can convert serial data received from an LCD controller to parallel data and then send them out as LCD driving waveforms to the LCD panel.| Part No. | HT1602 |

GENERAL DESCRIPTION
The HT1602 can be applied up to 1/64 duty. Furthermore, the bias voltage which determines the LCD driving voltage can be optionally supplied from an external source, thus the chip is suitable for driving various types of LCD panel. These special features increase the versatility of the chip.
