1 General description
The 74ALVCH162244 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 74ALVCH162244 is designed with 30 Ω series resistors in both HIGH and LOW
output states.
The 74ALVCH162244 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.
