1. General description

The 74LVT16244B is a 16-bit 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 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. Bus hold data inputs eliminate the need for

external pull-up resistors to define unused inputs
