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 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.

NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi + S (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacitance in pF; fo = output frequency in MHz; VCC = supply voltage in V; S (CL x VCC2 x fo) = sum of outputs.
