      These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for  use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.

       The 74AVCH16244 is a 16bit non-inverting buffer/line driverwith3 stateoutputs.Thedevicecanbeusedasfour 4bit buffers, two 8bit buffers or one 16-bit buffer.

      The3-state outputs are controlled by the output enable  inputs nOE.A HIGH on nOE causes the outputs to a ssume nputsn a high impedance OFF-state.

      The74AVCH16244isdesignedtohaveanextremelyfast propagation delay and a minimum amount of power consumption.

      To ensure the high-impedance output state during power-up or power-down, n OE should be tied to VCC through a pull-up resistor (Live Insertion).

      A Dynamic Controlled Output(DCO) circuitry of the 74AVCH16244 is implemented to support termination line drive during transient (seeFigs1and2).

      The 74AVCH16244 has active bus-hold circuitry 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.
