Product Overview: SN74LVTH162244 from Texas Instruments

The SN74LVTH162244 from Texas Instruments is a high-performance, 16-bit buffer and line driver designed for use in 3.3-V systems. It features 16 non-inverting buffers with 3-state outputs, making it an ideal choice for driving bus lines or buffering memory address registers. This integrated circuit (IC) is part of the LVTH family, which is characterized by its low-voltage operation and high tolerance to voltage variations, ensuring reliable performance in demanding applications.

The device is organized as four 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the input to the output. When OE is high, the output is in a high-impedance state, which is essential for bus-driving applications. This allows multiple outputs to be connected to a bus without causing conflicts. The SN74LVTH162244 is designed to be used with a 3.3V power supply but can also interface with 5V signals, providing a bridge between different voltage domains.

Key features of the SN74LVTH162244 include its support for mixed-mode signal operation, which allows it to interface with both 3.3V and 5V logic levels without the need for external components. The device also boasts a high drive capability, with -32mA Io (Output Current) and 64mA Ioss (Off-State Output Current). These features make the SN74LVTH162244 particularly suitable for implementing buffer registers, memory address drivers, and other bus-oriented systems.

The IC is available in a variety of packages, including the 48-pin Thin Shrink Small-Outline Package (TSSOP), 48-pin Thin Quad Flat Pack (TQFP), and 48-pin Very Thin Quad Flat Pack (VQFN). This range of packaging options provides flexibility for different space constraints and assembly processes.

Overall, the SN74LVTH162244 is a robust and versatile component that provides a reliable solution for high-speed digital interfacing. Its ability to handle both 3.3V and 5V logic levels, along with its high drive strength and bus-friendly architecture, makes it a valuable asset in a wide range of electronic systems.
