UC1711 and UC3711 are dual channel ultra-high-speed FET drivers with 25ns rise and fall time, 15ns propagation delay, 1.5A output drive capability, and a supply voltage range of 5V to 35V. They are made with a high-speed Schottky NPN process to optimize switching speed, temperature stability, and radiation resistance. These devices have inverting logic, TTL-compatible inputs, and output stages that can either source or sink current in excess of 1.5A with minimal cross-conduction charge. The channels are well matched and can be paralleled for doubled output current capability.
The Unitrode UC1711 family of FET drivers are made with an all-NPN Schottky process to optimize switching speed, temperature stability, and radiation resistance. These devices implement inverting logic with TTL compatible inputs and output stages that source or sink in excess of 1.5A of load current with minimal cross-conduction charge.
The document provides absolute maximum ratings, electrical characteristics, and switching characteristics for the UC1711 and UC3711 models. The UC1711 operates in a temperature range of -55°C to +125°C, while the UC3711 operates from 0°C to +70°C.
