Working Principles

The SN74LVTH540PWR is designed to translate logic levels between different voltage domains. It operates by receiving input signals from one voltage domain and producing output signals compatible with another voltage domain. The non-inverting nature of the inputs and outputs ensures that the logic states are preserved during translation. The tri-state outputs allow multiple devices to share a common bus, enabling efficient communication.
