Working Principles

The 74ABT125D/AUJ operates as a non-inverting buffer with 3-state outputs. When the Output Enable (OE) pin is high, the outputs are in the high-impedance state, allowing multiple devices to share a common bus without interference. The device amplifies and buffers input signals, providing signal integrity and isolation.
