Working Principles

SN74HC125DG4 works by receiving an input signal and buffering it before transmitting it to the output. The enable inputs control whether the outputs are active or in a high-impedance state. When the enable input is high, the outputs follow the input signals. When the enable input is low, the outputs enter a high-impedance state, effectively disconnecting them from the circuit.

SN74HC125DG4 finds applications in various fields, including:

1. Digital communication systems
2. Microcontroller-based projects
3. Industrial automation
4. Robotics
5. Automotive electronics
