带三态输出的单缓冲器
The is a high-speed Si-gate CMOS non-inverting Bus Buffer/Line Driver with 3-state output. The 3-state output is controlled by the output enable input pin OE. A LOW at pin OE causes the output as assume a high-impedance OFF-state. The HC device has CMOS input switching levels and supply voltage range 2 to 6V. The bus driver output currents are equal to those of the 74HC126.
