This 32-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVC32244 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 eight 4-bit buffers, four 8-bit buffers, two 16-bit buffers, or one 32-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 these devices as translators
in a mixed 3.3-V/5-V system environment. …
