The device can be used as four 4-bit buffers, two
8-bit buffers, or one 16-bit buffer. It provides true
outputs
and
symmetrical
active-low
output-enable (OE) inputs.
To ensure the high-impedance state during power
up or power down, OE should be tied to V
CC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.
The SN74ALVC16244A is characterized for
operation from –40°C to 85°C.
