FEATURES
DESCRIPTION
• Wide operating voltage: 1.0 to 5.5 V
• Optimized for Low Voltage applications: 1.0 to 3.6 V
• Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
• Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V,
The 74LV125 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT125.
The 74LV125 consists of four non-inverting buffers/line drivers with
3-state outputs. The 3-state outputs (nY) are controlled by the output
enable input (nOE). A HIGH at nOE causes the outputs to assume a
high impedance OFF-state.
Tamb = 25°C.
• Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V,
Tamb = 25°C.
• Output capability: bus driver
• ICC category: MSI

NOTE:
1. CPD is used to determine the dynamic power dissipation (PD in µW)
PD = CPD × VCC2 × fi (CL × VCC2 × fo) where:
fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
(CL × VCC2 × fo) = sum of the outputs.

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
