1. General description

The 74LVT245 is an 8-bit transceiver with 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

2. Features and benefits
