74AC16244 16-Bit Buffer/Line Driver
The 74AC16244 from Texas Instruments is a 16-bit non-inverting buffer/line driver designed to provide high-performance bus interface buffering for a wide range of applications. This integrated circuit is part of the 74AC family, known for its high-speed CMOS technology.
Equipped with two separate enable inputs (nOE1 and nOE2), the 74AC16244 allows each 8-bit section to be independently controlled, making it highly versatile for systems that require isolated data path control. The device operates over a broad voltage range of 2V to 6V and features edge-rate control circuitry that significantly enhances its performance in high-speed environments.
The 74AC16244 is designed with a bus-hold feature, which eliminates the need for external pull-up or pull-down resistors and ensures that the outputs remain at a last known state if left floating. This function is particularly useful in multiplexed bus applications where the data lines are often tri-stated.
With its low static and dynamic power consumption, the 74AC16244 is an energy-efficient choice for modern electronic systems. The device's inputs are also designed to withstand static discharge events, providing a high level of protection against the rigors of real-world usage.
Key features of the 74AC16244 include:
- 16-bit non-inverting buffer logic
- Independent enable controls for each 8-bit section
- Wide operating voltage range: 2V to 6V
- Edge-rate control circuitry for improved signal integrity
- Bus-hold feature on data inputs
- Low static and dynamic power consumption
- ESD protection for enhanced reliability
- Industry-standard footprint for easy integration
Whether used in high-speed data paths, address drivers, or as memory control buffers, the 74AC16244 is an excellent choice for designers looking for a robust, high-performance buffer/line driver. Its compatibility with a wide range of operating voltages and enhanced protection features make it suitable for a variety of industrial, commercial, and telecommunications applications.
