74AC11244数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The 74AC11244 is an octal buffer or line driver designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as two 4-bit buffers or one 8-bit buffer, with active-low output-enable (OE\\) inputs. When OE\\ is low, the device passes noninverted data from the A inputs to the Y outputs. When OE\\ is high, the outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, OE\\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The 74AC11244 is characterized for operation from -40°C to 85°C.
