Working Principles

The SN74HCT541DW is designed to provide logic level translation and signal buffering. It operates by receiving input signals on the A1-A6 and B1-B6 pins, which are then amplified and inverted internally. The non-inverted outputs Y1-Y5 are available when the output enable (OE) pin is low. When the OE pin is high, the outputs are in a high-impedance state, allowing other devices to drive the shared bus.
