General 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.
