DESCRIPTION
The 74ALVCH16825 is an 18–bit non-inverting buffer/driver with 3-State outputs for bus-oriented applications. The 74ALVCH16825 consists of two 9-bit sections with separate output enable signals. For either 9-bit buffer section, the two output enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must both be LOW for corresponding D outputs to be active. If either output enable input is HIGH, the outputs of that 9-buffer section are in the high impedance state. The 74ALVCH16825 has active bus hold circ……
