The ISL24011 is a high voltage TFT-LCD logic driver with
+40V and -20V output voltage swing capability. It is
manufactured using Intersil’s proprietary monolithic high
voltage bipolar process and is capable of driving a 4700pF
load in 500ns.
The ISL24011 will level shift a digital input signal to an output
voltage nearly equal to its output supply voltages. The
ISL24011 has 3 supplies. V
ON1

The ISL24011 is an octal voltage level shifter. The part was
designed to level shift a digital input signal to +22V and -5V
for TFT-LCD displays and is capable of level shifting input
logic signals (0V to 5.5V) to outputs as large as +40V and
-20V.
Power Supply Decoupling
The ISL24011 requires a 1.0µF decoupling capacitor as
close to the V
possible, for a large load equal to 5kΩ in parallel with
4700pF (Figure 16). This will reduce any dv/dt between the
different supplies and prevent the internal ESD clamp from
turning on and damaging the part.
For lighter loads such as a series 200Ω resistor and a
3300pF capacitance, the decoupling capacitors can be
reduced to 0.47µF.

Latch-up Proof
The ISL24011 is manufactured in a high voltage DI process
that isolates every transistor in its own tub making the part
latch-up proof.
Input Pin Connections
Unused inputs must be tied to ground. Failure to tie unused
input pins to ground will result in 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.

The ESD protection scheme is based on diodes from the
pins to the V
supply and a dv/dt-triggered clamp. This
ON2
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

should be employed to ensure the rate of rise is not
