NXP 74ALVC16244 16-bit Buffer/Line Driver
The NXP 74ALVC16244 is a high-performance, 16-bit buffer and line driver designed to address the needs of high-speed signal transmission while maintaining low power consumption. This integrated circuit is part of the Advanced Low-Voltage CMOS (ALVC) family, which is well-suited for interfacing with 3.3V systems in a wide range of applications including telecommunications, computing, and industrial equipment.
Featuring a wide voltage range, the 74ALVC16244 operates between 1.65V and 3.6V, which allows for interfacing with both 3.3V and 2.5V logic levels. This versatility ensures that the device can be used in mixed-voltage environments, providing a seamless bridge between different logic families.
The device is organized as dual octal buffers and line drivers with 3-state outputs. Each byte has separate output-enable (OE) inputs which can be used to place the eight outputs in either a normal logic state or a high-impedance state. In the high-impedance state, the outputs neither load the bus nor drive it, effectively allowing multiple devices to share the same bus lines without interference.
Key features of the NXP 74ALVC16244 include:
- High-speed performance with a maximum propagation delay of 3.8ns at 3.3V, which is critical for high-speed data transmission.
- Low power consumption, with a typical I_CC of only 40μA, minimizing power usage in battery-powered and power-sensitive applications.
- Bus hold on data inputs, which eliminates the need for external pull-up or pull-down resistors, simplifying board design and reducing component count.
- Wide bus-handling capability, with 16-bit wide data paths for efficient data transfer and processing.
- Multiple package options, including the TSSOP48 and SSOP48, providing flexibility for different board layouts and space constraints.
The 74ALVC16244 is a reliable and robust choice for system designers who require a high-speed, low-power buffer and line driver. Its advanced features ensure compatibility with modern high-speed logic systems, making it an essential component for a wide array of electronic designs.
