LCX024AK
Level Conversion Circuit
The LCX024AK has a built-in level conversion circuit in the clock input unit located inside the panel. The circuit
voltage is stepped up to V
DD
inside the panel. This level conversion circuit meets the specifications of a 3.0V
power supply of the externally-driven IC.
1. I/O characteristics of level conversion circuit
(For a single-phase input unit)
An example of the I/O voltage characteristics of a
level conversion circuit is shown in the figure to the
right. The input voltage value that becomes half the
output voltage (after voltage conversion) is defined
as Vth.
The Vth value varies depending on the V
DD
voltage.
The Vth values under standard conditions are
indicated in the table below. (HST, VST, EN, CLR,
RGT, VCK and BLK in the case of a single-phase input)

(For a differential input unit)
An example of I/O voltage characteristics of a level
conversion circuit for a differential input is shown in
the figure to the right. Although the characteristics,
including those of the Vth voltage, are basically the
same as those for a single-phased input, the two-
phased input phase is defined. (Refer to clock
timing conditions.)

2. Current characteristics at the input pin of level conversion circuit
A slight pull-in current is generated at the input pin
of the level conversion circuit. (The equivalent
circuit is shown to the right.) The current volume
increases as the voltage at the input pin decreases,
and is maximized when the pin is grounded. (Refer
to electrical characteristics.)
