Working Principles

The SN74AS241ANSRE4 is an 8-bit buffer/driver IC that operates as a non-inverting logic gate. It takes input signals from A1 to A7 and provides corresponding buffered outputs from Y1 to Y8. The OE (Output Enable) pin controls the tri-state operation, allowing the outputs to be disabled when necessary.

When the OE pin is low, the outputs are enabled and mirror the inputs. Conversely, when the OE pin is high, the outputs enter a high-impedance state, effectively disconnecting them from the circuit. This feature enables multiple devices to share a common bus without interfering with each other's signals.
