Working Principles

The SN74ALVCH16601DGVR is a universal bus transceiver that facilitates logic level shifting between two independent buses operating at different voltage domains. It uses non-inverting buffers to ensure bidirectional data flow without altering the logical state of the signals.

The device operates by receiving data from one bus and transmitting it to the other bus, or vice versa, depending on the control inputs. The voltage translation is achieved through level shifters that convert the input signals to the appropriate voltage levels of the target bus.
