For either 8-bit buffer section, the two output-enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must both be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 8-bit buffer section are in the high-impedance state. 54ACT16541, 74ACT16541 16-BIT BUFFERS/DRIVERS WITH 3-STATE OUPUTS SCAS208A – JUNE 1992 – REVISED APRIL 1996 54ACT16541 . . .
