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 and 2OE. 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 5V tolerant inputs.
