AVC family overview

NXP delivers the world's fastest CMOS logic family, the Advanced Very-low-voltage CMOS (AVC) family. The AVC family achieves speeds of less than 1.5ns at 3.3V and less than 2ns at 2.5V.

The AVC family features our Dynamic Control Output circuit (DCO, patent pending). The DCO circuit maintains the optimum current for achieving the highest signaling speeds while automatically reducing the output impedance during signal transitions. This reduces the undershoot and overshoot effects that become critical in very-high-speed system environments, eliminating the need for series damping resistors.

Moreover, with 3.3V, 2.5V, and 1.8V interfacing capabilities, AVC readily supports mixed-voltage environments. Our AVC family also offers a power-off feature that disables the outputs of the device when no power is applied, thus allowing live insertion.

New high-performance applications will benefit from the AVC family's performance. While at the same time, existing applications will find an easy upgrade path to the AVC family from lower-speed logic families.
