74LVC125A
Rev. 8 — 5 May 2020
Quad buffer/line driver with 5 V tolerant input/outputs; 3-state
Product data sheet
1. General description
The 74LVC125A consists of four non-inverting buffers/line drivers with 3-state outputs (nY) that
are controlled by the output enable input (nOE). A HIGH at nOE causes the outputs to assume a
high-impedance OFF-state.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to
the outputs.
2. Features and benefits
