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
