The SN74AVC1T45DBVR is an Octal Translating Transceiver with 4-bit IO-LVCMOS Level Shifting and flexible direction control for different logic inputs. It is capable of translating between 4V to 1.8V LVCMOS I/O with two voltage domains. It is built with two integrated transceivers. Each function with eight read and eight write D-type ports.

The SN74AVC1T45DBVR provides bidirectional voltage level translations between 4V and 1.8V logic interfaces. It can transparently transmit data without the need of external logic and direction control. Further, it helps reduce power consumption and board space. This device simplifies the design and saving time and money.

The SN74AVC1T45DBVR is integrated with a low-voltage translator. The low-voltage translator performs the necessary level shifting to transfer data between voltage domains. This device is composed of dual 8-Group to 8-Group buffers. Each group is composed of an LVCMOS input port, a 1.8V output port, a 2.5V IO-LVCMOS port, and a 4.5V IO-LVCMOS port.

The SN74AVC1T45DBVR has two command control inputs - Direction Control (DIR) and Master Output Enable (OE). DIR allows the device to operate in a transparent mode and OE enables the transfer of data from the high-voltage side to the low-voltage side. It also has two integrated input pins - Data Inhibit (DINH) and Data Output Enable (DOE). DINH and DOE determine the state of the port in either a 1.8V or 4V interface.

The SN74AVC1T45DBVR is a logic-level translator and level shifter combined in one package. This device is used in interfacing between low-voltage 1.8V logic circuits and high-voltage 4V logic circuits. It is used in applications such as power supply signaling, battery-powered controls, handheld and portable systems, display resolution controllers and LCD driver boards.

The SN74AVC1T45DBVR is a very useful device for reducing power consumption, board space, and component count in mixed voltage systems. This device efficiently bridges two separate logic and voltage worlds together.
