1. General description
The 74LVT2245; 74LVTH2245 is an 8-bit transceiver with 30 Ω termination resistors and 3-state
outputs. The device features an output enable (OE) and send/receive (DIR) for direction control.
A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Bus hold data inputs
eliminate the need for external pull-up resistors to define unused inputs
