Working Principles

The MC100EL31DR2G is a logic level translator that converts signals between different voltage domains. It operates by using differential inputs and outputs, which provide improved noise immunity compared to single-ended interfaces. The device accepts two input signals, P and R, and translates them to complementary outputs Q and /Q. The translation is performed based on the voltage levels of the VCC and VEE power supplies.
