Dual, High Speed MOSFET Driver

ISL55110, ISL55111

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, 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, 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 anti-phase.

ISL55110 and ISL55111 have 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.
