Working Principles

The SN74ALVCH162244GR operates by receiving input signals from one voltage domain and translating them to the corresponding logic levels in another voltage domain. It uses a combination of transistors and logic gates to achieve this level translation. The 3-state outputs allow the device to disconnect from the bus when not actively driving it, preventing conflicts with other devices connected to the same bus.
