Application Information
General
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 VON1, VON2 and VOFF power supply pins, as
possible, for a large load equal to 5k
Ω 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 200
Ω resistor and a
3300pF capacitance, the decoupling capacitors can be
reduced to 0.47µF.
Power Supply Sequence
The ISL24011 requires that VON2 be greater than or equal to
VON1 at all times. Therefore, if VON1 and VON2 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 VON1 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 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.
