Other Parts Discussed in Thread: SN74LVC32A, SN74LVC2G00, SN74HC32
Hi team
Do we have any integrated solution for this logic: CS5=!(!CS*A2*!A1*A0*!RD)?
Thanks,
Cera

Hi Cera,
We don't have a single chip solution for such a complex logic function, however, DeMorgan’s Theorem allows for a quick simplification that will reduce the above equation to only need two standard logic devices:
CS5 = !( CS + A1 + RD + !( A0 * A2 ) )
I have made a simplified schematic to show the required gates:
Depending on the voltage range requirements, the OR gates could come from an SN74LVC32A (1.8-3.3V) or an SN74HC32 (5V), and the NAND gates would be best from SN74LVC2G00.
