The SN74LVCC4245APW is a logic translator, level shifter that helps in converting digital signals from one voltage level to another. The device is one of Texas Instruments\' long-line of special purpose devices (SPDs) specifically designed for the automotive market. It is certified by the Automotive Electronics Council (AEC) and complies with the California Energy Commission (CEC) regulations. This device pairs an input buffer with a selectable logic level translator to provide an interface between circuit designs with a different logic voltage level while maintaining the input signal integrity and switching characteristics.

The SN74LVCC4245APW has 4 channels of 45-ohm bus transceivers able to isolated two sets of LVTTL and CMOS bus nodes allowing for level translation between two different voltage states. The device is available in a tiny 24-pin VSSOP package, with a low profile of 2.00mm (0.080"), making it well suited for high-density applications. It is also capable of operating at temperatures ranging from -40℃ to +85℃.

The SN74LVCC4245APW is designed to provide enhanced performance and reliability for level shifting from 1.8V LVTTL to 3.3V low-voltage CMOS logic. The core of the device consists of a full-duplex, open-collector line transceiver design, providing bidirectional level shifting between the two logic families. The output line drivers are touchpad-sensitive, and as such, have very low on-responding outputs (VIH and VOH) and very high off-state output current capability. The device also has a maximum on-state output resistance of 45Ω.

The SN74LVCC4245APW also features integrated thermal shutdown circuitry, which helps to reduce the power dissipation and protect the device in the event of an over temperature condition. The level shifting logic is configured with simple logic and allows for the input logic levels to be directly converted to the opposite voltage level.

The SN74LVCC4245APW can be used in applications such as Multi-voltage Bus-level Translators, Level Shifting/Translators, LVDS Bus Switches, and Step-Down Level Shifters between 1.0V and 3.3V signals. Potential applications include network hubs and routers, 3.3/5.0V-based processor systems, portable computing, medical imaging, and automated test equipment.

In conclusion, the SN74LVCC4245APW is a flexible and versatile logic translator, level shifter designed for the automotive market. It provides the the necessary circuitry for level shifting between two different voltage states. The device is available in a tiny 24-pin VSSOP package, and it is designed for high-density applications. Its touchpad-sensitive output line drivers provide very low on-responding outputs and very high off-state output current capability. The SN74LVCC4245APW device is suitable for applications such as Multi-voltage Bus-level Translators, Level Shifting/Translators, LVDS Bus Switches, and Step-Down Level Shifters between 1.0V and 3.3V signals. All these factors make the SN74LVCC4245APW a great choice for automotive applications.
