描述 Description

The 74AHC244Q is an octal buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The 1OE and 2OE are two output enable inputs, and each controls four of the 3-state outputs. When nOE is set high, the outputs are in high-impedance state. When nOE is set low, data transmits from the nAn inputs to the nYn outputs.
The over-voltage tolerant inputs can come up to 5.5V. With this function, this device can be used as a translator in mixed voltage environment.
This device is AEC-Q100 qualified (Automotive Electronics Council Standard Q100 Grade 1) and the use of this device is suitable for automotive applications.
