CMOS IC
LC4102C-T2A
LCD Dot Matrix Common Driver for STN Displays
Preliminary
Overview
Features
The LC4102C-T2A is a common driver for large-scale dot
matrix LCD panels. It includes a 160-bit bidirectional shift
register and 4-level LCD driver circuits. The number of
bits can be further increased by using the provided input
and output pins to connect multiple LC4102C-T2A in
cascade. The LC4102C-T2A and the LC4104C-T2A LCD
dot matrix segment driver IC form a large-screen LCD
panel driver chip set.
• Fabricated in a CMOS (P-sub) high-voltage process.
• LCD drive voltage: 36 V
• Logic system power-supply voltage: 2.7 to 5.5 V
• fcp max: 2.5 MHz
• Bidirectional shift register
• The shift register can be split into two 80-bit registers.
(Two screens drivable)
• DISPOFF function that locks the drive voltages output
to the LCD at fixed levels.
• Display duty: 1/160 to 1/480
• Package: TCP (Tape Carrier Package)
