Each output is disabled when the associated output-enable (OE) input is low. When OE is high, the respective gate passes the data from the A input to its Y output. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. 1 14 2 13 3 12 4 11 5 10 6 9 7 8 VCC 4OE 4A 4Y 3OE 3A 3Y 1A 1OE NC VCC 4OE SN54AHC126 . . .
