High Voltage TFT-LCD Logic Driver
The ISL24011 is a high voltage TFT-LCD logic driver with a
+40V and -20V (momentary absolute max) 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 and V_ON2 are positive
supplies with a voltage range between +10V and +40V
(absolute max). V_OFF is the negative supply with a voltage
range between -5V and -20V (absolute max). Outputs 1
through 6 are connected to V_ON1 and V_OFF. Outputs 7 and 8
are connected to V_ON2 and V_OFF. 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. V_ON2 should remain constant. It is
possible to tie V_ON1 and V_ON2 supplies together, if
independent control as described above is not desired.
V_ON2 is required to be greater than or equal to V_ON1 at all
times.
The ISL24011 is available in a 20 Ld TSSOP package. It is
specified for operation over the -40°C to +85°C industrial
temperature range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
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.
