  4. FAMILY RECOMMANDATION • Bipolar families : Saturation or decline phase Not recommended for new designs Recently discontinued (LTB = 30/04/01) • 5V CMOS families : maturity or saturation phase except for AHC/AHCT and VHC/VHCT Not recommended for new designs new designs

  5. FAMILY USED RECOMMANDATION • BiCMOS families : maturity phase for ABT • growth phase for LVT (3.3V) and ALVT (2.5V). new designs • 3.3V CMOS families : growth phase. Pay attention with FCT3 New designs
