Tamb = 25°C. DESCRIPTION The 74LV27 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT27. The 74LV27 provides the 3-input NOR function. CONDITIONS CL = 15 pF; VCC = 3.3 V See Notes 1 and 2 TYPICAL 8 3.5 24 UNIT ns pF pF NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in µW) PD = CPD × VCC2 × fi )ȍ (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF; fo = output frequency in MHz; VCC = supply voltage in V; ȍ (CL × VCC2 × fo) = sum of the outputs. 2. The condition is VI = GND to VCC. ORDERING INFORMATION PACKAGES 14-Pin Plastic DIL 14-Pin Plastic SO 14-Pin Plastic SSOP Type II 14-Pin Plastic TSSOP Type I TEMPERATUR...
