SN74ALVC244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

This octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operation.

The SN74ALVC244 is organized as two 4-bit line drivers with separate output-enable (OE)\\ inputs. When OE\\ is low, the device passes 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.
