Working Principles

The SN74AHCT126DRE4 operates as a quad bus buffer gate. It takes input signals from the A1, A2, B1, B2, C1, and C2 pins and provides buffered outputs on the Y1, Y2, Y3, and Y4 pins. The output enable (OE) pin controls the output state, while the input enable (G) pin determines whether the inputs are active or not. When the OE pin is low, the outputs are enabled, and the inputs are active when the G pin is high.

Detailed Application Field Plans

The SN74AHCT126DRE4 can be used in various applications, including but not limited to:

1. Data communication systems
2. Industrial automation
3. Automotive electronics
4. Consumer electronics
5. Medical equipment
