DESCRIPTION:

This 16-bit buffer/driver is built using advanced dual metal CMOS technology. The ALVCH16244 is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and busoriented 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 ALVCH16244 has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance.

The ALVCH16244 has “bus-hold” which retains the inputs’ last state whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors.
