DESCRIPTION:

This 16-bit buffer/driver is built using advanced dual metal CMOS

technology. The ALVC16244A 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.

The ALVC16244A has been designed with a ±24mA output driver. This

driver is capable of driving a moderate to heavy load while maintaining

speed performance.
