Working Principles

The PI90LV027AW is a signal level translator integrated circuit designed to convert digital signals between different voltage levels. It operates by receiving an input signal at one voltage level and translating it to the desired output voltage level. The device utilizes differential signaling, which provides improved noise immunity and signal integrity.

The IC requires two supply voltages, VCC1 for the input side and VCC2 for the output side. The input signal is received through IN1 and translated to the corresponding output signal at OUT1. Similarly, IN2 is used for the second input signal, which is translated to OUT2. The device ensures reliable signal translation with minimal propagation delay and output skew.
