Working Principles

The TC74VHC125FTELM is a quad bus buffer that operates by receiving input signals and providing buffered output signals. The output enable control input (OE) determines whether the outputs are active or in a high-impedance state. When OE is low, the outputs are enabled and mirror the input signals. Conversely, when OE is high, the outputs are disabled and enter a high-impedance state.

The TC74VHC125FTELM can be used in various applications, including:

1. Microprocessor-based systems
2. Data communication systems
3. Industrial automation equipment
4. Automotive electronics
5. Consumer electronics
6. Test and measurement instruments
7. Medical devices
