They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT125 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 HIGH at nOE causes the outputs to assume a HIGH impedance OFF-state. The 125 is identical to the 126 but has active LOW enable inputs.

C is used to determine the dynamic power dissipation (P in W): PD D 2 2 P = C V f + (C V f ) where: D PD CC i L CC o f = input frequency in MHz i f = output frequency in MHz o C = output load capacitance in pF L V = supply voltage in V CC 2 (C V f ) = sum of outputs L CC o 2. For HC the condition is V = GND to V I CC For HCT the condition is V = GND to V - 1.5 V I CC ORDERING INFORMATION See 74HC/HCT/HCU/HCMOS Logic Package Information. December 1990 2
