SN74ABT2827 具有三态输出的 10 位缓冲器/驱动器
SN74ABT2827 描述
These 10-bit buffers or bus drivers provide a high-performance bus interface for wide data paths or buses carrying parity.
The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (
or 
) input is high, all ten outputs are in the high-impedance state. The 'ABT2827 provide true data at their outputs.
To ensure the high-impedance state during power up or power down, 
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 outputs, which are designed to source or sink up to 12 mA, include equivalent 25-Ω series resistors to reduce overshoot and undershoot
