ISL24010
for TFT/LCD Panels
FN6124.0
High Voltage TFT-LCD Logic Driver
Features
The ISL24010 is a high voltage TFT-LCD logic driver with a
+40V and -20V (momentary absolute max) output voltage
swing capability. It is manufactured using the Intersil’s
proprietary monolithic high voltage bipolar process and is
capable of driving a 3000pF load in 500ns.
• 0V to 5.5V (absolute max) Input Voltage Range
The ISL24010 will level shift a digital input signal to an output
voltage nearly equal to its output supply voltages. The
ISL24010 has 3 supplies. VON1 and VON2 are positive
supplies with a voltage range between +10V and +40V
(absolute max). VOFF is the negative supply with a voltage
range between -5V and -20V (absolute max). Outputs 1
through 6 are connected to VON1 and VOFF. Outputs 7 and 8
are connected to VON2 and VOFF. This configuration
enables outputs 1 through 6 to provide slicing to the row
drivers to reduce flicker, and outputs 7 and 8 to control
possible supply lines. VON2 should remain constant. It is
possible to tie VON1 and VON2 supplies together, if
independent control as described above is not desired.
VON2 is required to be greater than or equal to VON1 at all
times.
The ISL24010 is available in TSSOP-20 pin package. It is
specified for operation over the -40°C to +85°C industrial
temperature range.

material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.

Application Information
General
The ISL24010 is an Octal voltage level shifter. The part was
designed to level shifts a digital input signal to +22V and -5V
for TFT-LCD displays. The device is capable of level shifting
a CMOS logic signal between +40V and -20V.
Power Supply Decoupling
The ISL24010 requires a 0.1F decoupling capacitor as
close to the VON1, VON2 and VOFF power supply pins for a
large load equal to 5k in parallel with 100pF (Figure 16).
This will deduce any dv/dt between the different supplies and
prevent the internal ESD clamp from turning on and
damaging the part.
Input Pin Connections
Unused inputs must be tied to ground. Failure to tie unused
input pins to ground will result in a rail to rail oscillations on
the respective output pins and higher unwanted power
dissipation in the part. Under these conditions, the
temperature of the part could get very hot.
Limiting the Output Current
No output short circuit current limit exists on this part. All
applications need to limit the output current to less than
80mA. Adequate thermal heat sinking of the parts is also
required.
Application Diagram (TV)
Power Supply Sequence
The ISL24010 requires that VON2 be greater than or equal to
VON1 at all times. Therefore, if VON1 and Von 2 are different
supplies, then VON2 needs to be turned on before VON1.
The reason for this requirement is shown in Circuit 4 in the
Pin Description Table. The ESD protection diode between
VON2 and Von 1 will forward bias if VON1 becomes a diode
drop greater than VON2. Recommended power supply
sequence: VON2, VON1, VOFF then input logic signals.
The ESD protection scheme is based on diodes from the
pins to the VON2 supply and a dV/dt- triggered clamp. This
dV/dt triggered clamp imposes a maximum supply turn-on
slew rate of 10V/µs. This clamp will trigger if the supply
powers up too fast, causing amps of current to flow. Ground
and VON1 are treated as I/O pins with this protection
scheme. In applications where the dV/dt supply ramp could
exceed 10V/µs, such as hot plugging, additional methods
should be employed to ensure the rate of rise is not
exceeded.
Latch-up Proof
The ISL24010 is manufactured in a high voltage DI process
that isolates every transistor in it’s own tub making the part
latch-up proof.
