SN74AHC126DBR

The ’AHC126 devices are quadruple bus buffer gates featuring independent line drivers with 3 - state outputs. 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.
