8.2.1 Design Requirements

To select proper device from UCC2742x-Q1 family, TI recommends first checking the appropriate logic for the outputs. The UCC27423-Q1 has dual inverting outputs, the UCC27424-Q1 has dual noninverting outputs, and the UCC27425-Q1 has an inverting channel A and noninverting channel B. Moreover, evaluate some considerations to make the most appropriate selection. Among these considerations are VDD, drive current, and power dissipation.
