Working Principles

The SN74ABT240ANSR is a non-inverting buffer/driver IC that amplifies and transfers digital signals. It operates by receiving input signals on the A1-A8 pins and producing amplified output signals on the Y1-Y8 pins. The OE pin controls the output enable function, allowing the device to be enabled or disabled.

When the OE pin is low, the outputs are active and reflect the logic levels of the corresponding inputs. When the OE pin is high, the outputs are in a high-impedance state, effectively disconnecting them from the bus.
