They are specified in compliance with JEDEC standard no. 7A. The HC/HCT126 are four non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs (nY) are controlled by the output enable input (nOE). A LOW at nOE causes the outputs to assume a HIGH impedance OFF-state. The "126" is identical to the "125" but has active HIGH enable inputs. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf = 6 ns TYPICAL SYMBOL PARAMETER CONDITIONS UNIT HC tPHL/ tPLH propagation delay nA to nY CI input capacitance CPD power dissipation capacitance per buffer CL = 15 pF; VCC = 5 V notes 1 and 2 Notes 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi + (CL x VCC2 x fo) where: fi = input frequency in MHz fo = output frequency in MHz CL = output load capacitance in pF VCC = supply voltage in V (CL x VCC2 x 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".
