LH1562
DESCRIPTION
The LH1562 is a 240-output segment/common
driver IC suitable for driving large/medium scale dot
matrix LCD panels, and is used in personal
computers/work stations. Through the use of SST
(Super Slim TCP) technology, it is ideal for
substantially decreasing the size of the frame
section of the LCD module. The LH1562 is good
both as a segment driver and a common driver,
and it can create a low power consuming, high-
resolution LCD.
FEATURES
• Number of LCD drive outputs : 240
• Supply voltage for LCD drive : +15.0 to +42.0 V
• Supply voltage for the logic system : +2.5 to +5.5 V
• Low power consumption
• Low output impedance
• Package : 269-pin TCP (Tape Carrier Package)
(Segment mode)
• Shift clock frequency
– 20 MHz (MAX.) : VDD = +5.0±0.5 V
– 15 MHz (MAX.) : VDD = +3.0 to +4.5 V
– 12 MHz (MAX.) : VDD = +2.5 to +3.0 V
• Adopts a data bus system
• 4-bit/8-bit parallel input modes are selectable with
a mode (MD) pin
• Automatic transfer function of an enable signal
• Automatic counting function which, in the chip
selection mode, causes the internal clock to be
stopped by automatically counting 240 bits of
input data
• Line latch circuits are reset when  active
(Common mode)
• Shift clock frequency : 4 MHz (MAX.)
• Built-in 240-bit bi-directional shift register
(divisible into 120 bits x 2)
240-output LCD Segment/Common
Driver IC
• Available in a single mode (240-bit shift register)
or in a dual mode (120-bit shift register x 2)
q Y1/Y240 Single mode
w Y240/Y1 Single mode
e Y1/Y120, Y121/Y240 Dual mode
r Y240/Y121, Y120/Y1 Dual mode
The above 4 shift directions are pin-selectable
• Shift register circuits are reset when 
active
