Working Principles
The SN74BCT540ANSR is a buffer/line driver IC that amplifies and transfers digital signals. It operates by receiving input signals on the A and B pins, and providing amplified output signals on the corresponding Y pins. The non-inverting nature of the buffer ensures that the output signal matches the input signal.
The tri-state outputs allow the device to be effectively disconnected from the bus when the output enable (OE) pin is set to a high logic level. This feature enables multiple devices to share the same bus without interfering with each other's signals.
