54ACT16541 Overview
The ’ACT16541 are noninverting 16-bit buffers posed of two 8-bit sections with separate output-enable signals. 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.
