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.

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.
