Working Principles

The MC74ACT125NG operates as a buffer/line driver, taking input signals and providing non-inverted outputs. It features 3-state outputs, which means the outputs can be disabled (high impedance state) when the output enable (OE) pin is set to a specific logic level. This allows multiple devices to share a common bus without causing contention issues.

The MC74ACT125NG is commonly used in various applications, including:

1. Data communication systems
2. Microprocessor-based systems
3. Industrial control systems
4. Automotive electronics
5. Instrumentation and measurement equipment
