description
These 16-bit buffers and bus drivers provide a high-performance bus interface for wide data paths. The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, all corresponding outputs are in the high-impedance state.
