FEATURES
DESCRIPTION
The 74LVC125A is a high performance, low-power, low-voltage
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
• 5-volt tolerant inputs/outputs, for interfacing with 5-volt logic
• Supply voltage range of 1.2V to 3.6V
• Complies with JEDEC standard no. 8-1A
• CMOS low power consumption
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.
• Direct interface with TTL levels
• High impedance when V = 0V

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.
