Working Principles

The SN74LVTH245AMDBREP is designed using CMOS technology, which allows it to operate at low voltages while providing high-speed performance. It consists of eight bidirectional buffers that can translate signals between two voltage domains. The direction of data flow is controlled by the Output Enable (OE) pin. When OE is low, the device is enabled, and data can flow in both directions. When OE is high, the device is disabled, and the outputs are in a high-impedance state.
