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.
DRIVE FEATURES:
• High Output Drivers: ±24mA
• Suitable for heavy loads
APPLICATIONS:
• 3.3V high speed systems
• 3.3V and lower voltage computing systems
