Working Principles

The SN74ALVTH16245KR is designed to facilitate bidirectional data transfer between two voltage domains. It utilizes level shifting techniques to ensure compatibility between different voltage levels. The device operates by enabling the appropriate output buffers based on the direction control signal. When the direction control is set to one direction, data from one domain is transferred to the other domain. Conversely, when the direction control is set to the opposite direction, data flows in the reverse direction.
