Working Principles

The SN74ABT5401DWG4 is a bi-directional voltage level translator that enables seamless communication between devices operating at different logic levels. It uses a combination of MOSFETs and CMOS technology to achieve fast and efficient level shifting.

The direction of translation is controlled by the DIR pin. When DIR is set to logic high, data is translated from Channel A to Channel B. Conversely, when DIR is set to logic low, data is translated from Channel B to Channel A.

The OE pin acts as an output enable control. When OE is set to logic low, the outputs are enabled and data can flow through the device. Conversely, when OE is set to logic high, the outputs are disabled, effectively isolating the channels.
