Working Principles

The 74LVX16245TTR operates by receiving input signals from one bus (A) and transmitting them to another bus (B), or vice versa. The direction of data flow is controlled by the output enable pins (OE). When the OE pins are active, the IC allows bidirectional data transfer. When the OE pins are inactive, the outputs are in a high-impedance state, effectively disconnecting the IC from the buses.
