74LVT245D集成電路（IC）的緩沖器驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

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
