74LVC16244A; 74LVCH16244A
Rev. 16 — 21 September 2021
16-bit buffer/line driver; 5 V input/output tolerant; 3-state
Product data sheet
1. General description
The 74LVC16244A; 74LVCH16244A 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. Inputs can be driven from either
3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V
and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input
rise and fall times. This device is fully specified for partial power down applications using I
OFF
. The
I
OFF
circuitry disables the output, preventing the potentially damaging backflow current through the
device when it is powered down.
The 74LVCH16244A bus hold on data inputs eliminates the need for external pull-up resistors to
hold unused inputs.
