HD66100F
(LCD Driver with 80-Channel Outputs)
Description
The HD66100F description segment driver with 80 LCD drive circuits is the improved version of the no
longer current HD44100H LCD driver with 40 circuits.
It is composed of a shift register, an 80-bit latch circuit, and 80 LCD drive circuits. Its interface is
compatible with the HD44100H. It reduces the number of LSI’s and lowers the cost of an LCD module.
Features
• LCD driver with serial/parallel converting function
• Interface compatible with the HD44100H; connectable with HD43160AH, HD61830, HD61830B,
LCD-II (HD44780), LCD-III (HD44790)
• Internal output circuits for LCD drive: 80
• Internal serial/parallel converting circuits
80-bit bidirectional shift register
80-bit latch circuit
• Power supply
Internal logic circuit: +5V ±10%
LCD drive circuit: 3.0V to 6.0V
• CMOS process

HD66100F
Pin Description
VCC, GND, VEE: VCC supplies power to the internal logic circuit. GND is the logic and drive ground. VEE
supplies power to the LCD drive circuit.
V1, V2, V3, and V4: V1 to V4 supply power for driving an LCD (Figure 2).
CL1: HD66100F latches data at the negative edge of CL1.
CL2: HD66100F receives shift data at the negative edge of CL2.
M: Changes LCD drive outputs to AC.
DI: Inputs data to the shift register.
DO: Output data from the shift register.
SHL: Selects a shift direction of serial data. When the serial data is input in order of D1, D2, ..., D79,
D80, the relation between the data and the output Y is shown in Table 3.
Y1–Y80: Each Y outputs one of the four voltage levels—V1, V2, V3, or V4—according to the
combination of M and display data (Figure 2).
NC: Do not connect any wire to these terminals.

Notes: 1. A reference point is GND (= 0V)
2. Applies to V1–V4.
Note: If used beyond the absolute maximum ratings, LSIs may be permanently destroyed. It is best to
use them at the electrical characteristics for normal operations. If they are not used at these
conditions, it may affect the reliability of the device.
