This 16-bit buffer/driver is designed for 1.65-V to
3.6-V VCC operation.
The SN74LVC16244A device is designed specifically to improve the performance and density
of 3-state memory address drivers, clock drivers, and bus-oriented receivers and
transmitters.
The SN74LVC16244A device can be used as four 4-bit buffers, two 8-bit buffers, or one
16-bit buffer. The device provides true outputs and symmetrical active-low output-enable
(OE) inputs.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of
this device as a translator in a mixed 3.3-V and 5-V system environment.
This device is fully specified for partial-power-down applications using
Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the
driver.
