74ALVCH16825
18-bit buffer/driver; 3-state
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 nYn 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 circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
