The 74HC/HCT125 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).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 controlledby the output enable input (nOE). A HIGH at nOE causes the outputs to assume a HIGH impedance OFF-state.The “125â€Â is identical to the “126â€Â but has active LOW enable inputs
