All logic cells in the tengen CIC...

C01: Y=(A&B)|(C&D)
C02: Y=A             (appears to be used only as a pin buffer)
C03: Y=~(A&B)
C04: Y=~(A|B)
C05: Y=(A^B)
C06: Y=~(A&B&C)
C07: Y=~A
C08: Y=~A
C09: Y=A             (appears to be a delay line- pinch resistor + capacitor)
C10: Y=A, Z=~A
C11: FF with async reset
C12: Y=~(A|B), Z=(~A)|B
C13: latch
C14: FF with async set+clear
C15: Y=~((A&B&C)|D)
C16: Y=A
C17: Y=~(A^B)
C18: latch with async clear
C19: Y=~((A&B)|(C&D))
C20: Y=~(A&B&C&D&E)
C21: Y=~(A|B|C)
