STMicroelectronics 74AC16244TTR: 16-Bit Buffer/Line Driver

The 74AC16244TTR from STMicroelectronics is a high-performance, 16-bit buffer and line driver designed to provide high-speed drive capabilities with robust performance. This integrated circuit is part of the 74AC series, which is renowned for its fast switching speeds and efficient power consumption. The device is specifically engineered to improve the signal integrity of high-speed buses and is an excellent choice for applications that require a reliable and strong signal driver.

Constructed with advanced CMOS technology, the 74AC16244TTR offers a significant advantage in both speed and power dissipation compared to its predecessors. It operates at a voltage range from 2V to 6V, making it versatile for use in various logic-level environments. The device features 16 non-inverting buffers with 3-state outputs, which allows for high drive capability and the flexibility to disable output when necessary, reducing the risk of bus contention.

The 74AC16244TTR comes in a TSSOP (Thin Shrink Small Outline Package) with 48 pins, providing a compact footprint for space-constrained applications. Its surface-mount design is suitable for automated assembly processes, and the device is characterized for operation from -40°C to 85°C, ensuring reliability across a wide range of temperature conditions.

Each buffer of the 74AC16244TTR is organized as two separate 8-bit sections with individual output-enable (OE) inputs. This allows for independent control of each section, providing the user with flexibility in managing different parts of the system bus or interface. The OE inputs are active-low, which simplifies the control logic design.

Applications for the 74AC16244TTR are diverse and include memory driving, address driving for memory-intensive applications, and input/output port expansion. Its high drive strength and fast edge rates make it ideal for interfacing with high-capacitance loads or low-impedance backplanes, ensuring signal integrity in the most demanding scenarios.

In summary, the STMicroelectronics 74AC16244TTR is a robust and high-performing buffer/line driver that is designed to meet the needs of modern high-speed digital systems. Its combination of speed, power efficiency, and design flexibility makes it a valuable component for any application requiring reliable signal driving capabilities.
