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.

Note:
4. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current
consumption without load.
Average operating current can be obtained by the eqation: ICC(opr.) = -C----P----D----×-4----V-(--p-C---e-C--r--,-×--b---f-i-I-tN--)---×-----I--C----C-
