ISL55110, ISL55111
Dual, High Speed MOSFET Driver
The ISL55110 and ISL55111 are dual high speed mosfet
drivers intended for applications requiring accurate pulse
generation and buffering. Target applications include
Ultrasound, CCD Imaging, Automotive Piezoelectric
distance sensing and clock generation circuits.
With a wide output voltage range and low on resistance,
these devices can drive a variety of resistive and capacitive
loads with fast rise and fall times, allowing high speed
operation with low skew as required in large CCD array
imaging applications.
The ISL55110 and ISL55111 are compatible with 3.3V and
5V logic families and incorporate tightly controlled input
thresholds to minimize the effect of input rise time on output
pulse width. The ISL55110 has a pair of in-phase drivers
while the ISL55111 has two drivers operating in antiphase.
Both inputs of the device have independent inputs to allow
external time phasing if required.
The ISL55110 has a power down mode for low power
consumption during equipment standby times, making it
ideal for portable products.
The ISL55110 and ISL55111 are available in 16 Ld Exposed
pad QFN packaging and 8 Ld TSSOP. Both devices are
specified for operation over the full -40°C to +85°C
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.
