They are specified in compliance with JEDEC standard no. 7A. The 74HC7266 provide the EXCLUSIVE-NOR function with active push-pull output. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns TYPICAL SYMBOL PARAMETER CONDITIONS UNIT HC tPHL/ tPLH propagation delay nA, nB to nY CI input capacitance CPD power dissipation capacitance per gate CL = 15 pF; VCC = 5 V note 1 Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi +∑ (CL × VCC2 × fo) where: fi = input frequency in MHz fo = output frequency in MHz CL = output load capacitance in pF VCC = supply voltage in V ∑ (CL × VCC2 × fo) = sum of outputs 2. For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC − 1.5 V ORDERING INFORMATION See “74HC/HCT/HCU/HCMOS Logic Package Information”.
