without using the internal D-type flip-flops by

simultaneously enabling GAB or GBA. In this

configuration each output reinforces its input.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

Figure 2: Input And Output Equivalent Circuit

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
