DESCRIPTION
The 74ALVC16244; 74ALVCH16244 is a 16-bit
non-inverting buffer/line driver with 3-state outputs. The
device can be used as four 4-bit buffers, two 8-bit buffers
or one 16-bit buffer. The 3-state outputs are controlled by
the output enable inputs 1OE, 2OE, 3OE and 4OE. A
HIGH on nOE causes the outputs to assume a
high-impedance OFF-state.
The 74ALVCH16244 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.
The 74ALVC16244 has 5 V tolerant inputs.
