Working Principles

The 74LVTH162244MEA is a logic level translator that allows communication between integrated circuits operating at different voltage levels. It uses a combination of voltage level shifters and non-inverting buffers to ensure bidirectional data flow with minimal delay.

The device operates by receiving input signals from one voltage domain and translating them to the corresponding voltage level in the target domain. The translated signals are then available at the output pins, which can be connected to other devices or systems.

The OE pins control the output enable function for each group of eight channels, allowing selective activation or deactivation of specific channels. This feature enables efficient bus sharing among multiple devices.
