QUADRUPLE BUS BUFFER
GATES WITH 3-STATE OUTPUTS
DESCRIPTION
The
U74AHCT126
are quadruple bus buffer gates featuring
independent line drivers with 3-state outputs. When OE is low, the nY
outputs are in a high-impedance state. When OE is high, the device
passes noninverted data from the nA input to its nY output.
To ensure the high-impedance state during power up or power
down, OE should be tied to GND through a pull-down resistor; the
minimum value of the resistor is determined by the current-sourcing
capability of the driver.
