Working Principles

The SN74ALVCH16827DGGR utilizes high-speed CMOS technology to perform voltage level translation. It consists of multiple bidirectional buffers that can translate signals between two voltage domains. The direction of translation is controlled by the OEAB and OEBA pins. When OEAB is low, the A-side inputs are enabled and translated to the B-side outputs. Conversely, when OEBA is low, the B-side inputs are enabled and translated to the A-side outputs. The Schmitt-trigger inputs ensure noise immunity by providing hysteresis.
