1. General description

The 74ABT162244 is a 16-bit buffer/line driver with 30 Ω termination resistors and 3-state outputs.

The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device

features four output enables (1OE, 2OE, 3OE and 4OE), each controlling four of the 3-state

outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. This device

is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the

output, preventing the potentially damaging backflow current through the device when it is powered

down.
