Product data sheet
1. General description
The 74LVC16244A; 74LVCH16244A are 16-bit non-inverting buffer/line drivers with
3-state bus compatible outputs. The device can be used as four 4-bit buffers, two 8-bit
buffers or one 16-bit buffer. It features four output enable inputs, (1OE to 4OE) each
controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a
high-impedance OFF-state.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs. These features allow the use of these devices in mixed
3.3 V and 5 V applications.
The 74LVCH16244A bus hold on data inputs eliminates the need for external pull-up
resistors to hold unused inputs.
