DESCRIPTION/ORDERING INFORMATION
This 16-bit buffer/driver is designed for 1.65-V to
3.6-V VCC operation.
The SN74LVC16244A is designed specifically to
improve the performance and density of 3-state
memory address drivers, clock drivers, and
bus-oriented receivers and transmitters.
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.
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/5-V system environment.
