74ALVC125
Quad buffer/line driver; 3-state
Rev. 02 — 10 January 2008
Product data sheet
1. General description
The 74ALVC125 is a quad non-inverting buffer/line driver with 3-state outputs. The 3-state
outputs (nY) are controlled by the output enable input (nOE). A HIGH on the nOE pin
causes the outputs to assume a high-impedance OFF-state.

The minimum input voltage ratings may be exceeded if the input current ratings are observed.
When V
CC
= 0 V (Power-down mode), the output voltage can be 3.6 V in normal operation.
For SO14 packages: above 70
°C
derate linearly with 8 mW/K.
For TSSOP14 packages: above 60
°C
derate linearly with 5.5 mW/K.
For DHVQFN20 packages: above 60
°C
derate linearly with 4.5 mW/K.
