74LV245PW集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

1. General description

The 74LV245 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. Inputs include clamp diodes. This enables the use of current limiting

resistors to interface inputs to voltages in excess VCC.

2. Features and benefits
