The Texas Instruments UC1714J is a buffer/inverter MOSFET driver designed to drive the gate of a discrete power MOSFET from a low-current logic signal. It accepts a single input and delivers a buffered or inverted output with enough peak current to charge the gate capacitance quickly, reducing switching losses. Typical applications include switch-mode power supplies, motor drives, and class-D audio amplifiers where a clean gate-drive waveform matters.
It is RoHS non-compliant, so designs requiring RoHS exemption documentation or legacy through-hole assembly flows should account for this.
