Working Principles

The SN74AHCT125RGYR operates as a buffer/line driver by taking input signals and providing amplified, non-inverted output signals. The active low output enable pins (OE) control the state of the outputs. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus. When OE is low, the inputs are transferred to the outputs with amplification.
