DESCRIPTION
The 74LVC125A is a high performance, low-power, low-voltage Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3V or 5.0V devices. In 3-state operation, outputs can handle 5V. The 74LVC125A 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.

NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in W) PD = CPD x VCC2 x fi ) (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL x VCC2 x fo) = sum of the outputs. 2. The condition is VI = GND to VCC

NOTES: 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.
