description/ordering information
This 16-bit buffer/driver is designed for 1.65-V to 3.6-V V
CC
operation.
The SN74LVCH162244A is designed specifically to improve both 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.
