74ALVC541
Octal buffer/line driver; 3-state
Rev. 02 — 5 November 2007
Product data sheet
1. General description
The 74ALVC541 is an octal non-inverting buffer/line drivers with 3-state bus compatible
outputs. The 3-state outputs are controlled by the output enable inputs OE0 and OE1.
A HIGH on OEn causes the outputs to assume a high-impedance OFF-state.
