74LVX125
Low Voltage Quad Buffer with 3-STATE Outputs
Features
Input voltage level translation from 5V to 3V
Ideal for low power/low noise 3.3V applications
Guaranteed simultaneous switching noise level and
dynamic threshold performance
General Description
The LVX125 contains four independent non-inverting
buffers with 3-STATE outputs. The inputs tolerate volt-
ages up to 7V allowing the interface of 5V systems to 3V
systems.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
