The ICL7667 is a dual monolithic high-speed driver designed to convert TTL level signals into high current outputs at voltages up to 15V. Its high speed and current output enable it to drive large capacitive loads with high slew rates and low propagation delays. With an output voltage swing only millivolts less than the supply voltage and a maximum supply voltage of 15V, the ICL7667 is well suited for driving power MOSFETs in high frequency switched-mode power converters. The ICL7667’s high current outputs minimize power losses in the power MOSFETs by rapidly charging and discharging the gate capacitance. The ICL7667’s inputs are TTL compatible and can be directly driven by common pulse-width modulation control ICs.
The ICL7667 is a dual monolithic high‑speed driver that converts TTL level signals into high‑current outputs up to 15 V. It is designed for driving power MOSFET gates in switched‑mode power supplies and other high‑frequency applications.
