74HC245BQ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 74HC245; 74HCT245 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 of VCC.
