Working Principles

The 74ACT11240DW is a non-inverting buffer/driver IC that amplifies and drives digital signals within a circuit. It operates by receiving input signals through the A1-A5 pins and providing amplified output signals through the Y1-Y4 pins. The OE1 pin controls the output state, allowing the device to be enabled or disabled.

When the OE1 pin is high, the outputs (Y1-Y4) are active and reflect the input signals. Conversely, when the OE1 pin is low, the outputs are in a high-impedance state, effectively disconnecting them from the circuit. This 3-state output feature enables multiple devices to share a common bus without interfering with each other.
