ACL: Advanced CMOS Logic

Almost ten years ago, the CMOS logic technology took a giant step forward with the introduction of the HC and HCT series. However, in the intervening years, it has become clear that even these fast logic devices can not replace all types of bipolar (TTL) circuit. The lntroductlon of the fourth CMOS generation, Advanced CMOS Logic. or ACl, means that now even the fastest TTL logic circuits, ALS, may be replaced by CMOS devices.
