1. General description
The 74LVT16244B; 74LVTH16244B 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
