General description
The 74LVC16244A-Q100; 74LVCH16244A-Q100 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-Q100 bus hold on data inputs eliminates the need for external pull-
up resistors to hold unused inputs.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
