Eight Transistor Tri-State Driver Implementing Cascade Structures To Reduce Peak Current Consumption, Layout Area and Slew Rate

摘要

An eight-transistor tri-state driver. The tri-state driver implements multiple cascade structures where each cascade structure may refer to a pair of complementary transistors serially connected. Each cascade structure may include a p-conductivity type transistor serially connected to a n-conductivity type transistor. By implementing cascade structures in a tri-state driver, there is a lower peak current consumption, a reduced slew rate as well as a reduction in the amount of layout area used in comparison to the classic tri-state drivers.
