3 Description
This 16-bit buffer/driver is designed for 1.65-V to
3.6-V V_CC operation. The device can be used as four
4-bit buffers, two 8-bit buffers, or one 16-bit buffer.
The SN74LVCH16244A device is designed
specifically to improve the performance and density of
3-state memory address drivers, clock drivers, and
bus-oriented receivers and transmitters.
