When disabled, both output transistors are turned off, presenting a high-impedance state to the bus so the output will act neither as a significant load nor as a driver.
The ’125 and ’LS125A devices’ outputs are disabled when G is high.
The ’126 and ’LS126A devices’ outputs are disabled when G is low.
