Working Principles

SN74ABT2245N operates by receiving input signals from one bus and transmitting them to the other bus bidirectionally. The non-inverting outputs ensure that the transmitted signals maintain their original logic levels. The 3-state outputs allow the device to be effectively disconnected from the bus when not in use, preventing interference and enabling multiple devices to share the same bus.
