(2) LCD drive output
The T6L24 has two sample-and-hold circuits called Sample-And-Hold (1) and (2).
These two circuits alternate between serving as the output and the sample-and-hold. Which circuit
fulfils which function is determined by the setting of the CX pin.

Sample-and-hold circuit (1)
The analog signal inputs VA, VB and VC are output as follows: VA is sent to the LCD driver output pins
SC1 to SC80, VB is sent to output pins SB1 to SB80, and VC is sent to output pins SA1 to SA80. The
analog signal inputs will be sent to LCD driver output pins by the setting of the CX pin as shown below:
Note: The CX pin setting must not be altered while the device is sampling data.
(3) Vertical shift data output
● When MODE
==== high
The output DO/I (U/D = high) or DI/O (U/D = low) is driven high for one clock period synchronously with
the rising CPH, one clock period before the data (which is to be output to (SA80, SB80, SC80) or (SA1,
SB1, SC1)) is latched into the shift register.
● When MODE
==== low
The output DO/I (U/D = high) or DI/O (U/D = low) is driven high for one clock period synchronously with
the rising CPH, one clock period before the data (which is to be output to SA80 or SC1) is latched into
the shift register.
When using two or more of these devices to drive a large screen, connect the vertical shift data output
from the first stage of the LCD driver directly to the vertical shift data input at the next stage. In this
way, the device’s LCD drive output pin can easily be expanded as necessary.
(4) Sample-and-hold reference voltage (C-COM)
The device’s sample-and-hold circuits are configured using the internal capacitors. The C-COM pin is
used to supply the reference voltage for these circuits. Apply stable DC voltage to the pin.
