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.
