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.

2 Features and benefits
