They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT14 provide six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns TYPICAL SYMBOL tPHL/ tPLH CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W): 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”.
