Working Principles

The SN74ABT126N is a buffer/driver IC that amplifies and isolates digital signals. It operates by receiving input signals on the A inputs and providing amplified outputs on the Y outputs. The G inputs control the tri-state outputs, allowing them to be enabled or disabled.

When the G inputs are high (logic 1), the outputs are active and reflect the input signals. When the G inputs are low (logic 0), the outputs are in a high-impedance state, effectively disconnecting them from the rest of the circuit.

Detailed Application Field Plans

The SN74ABT126N can be used in various applications, including:

1. Data communication systems
2. Microprocessor interfacing
3. Memory address decoding
4. Bus driving and buffering
5. Level shifting and voltage translation
