The SN74AHC244DWE4 from Texas Instruments is a high-performance, octal buffer and line driver designed to facilitate the interfacing between different voltage levels and to drive heavily loaded bus lines with high drive current capability. This integrated circuit is part of the AHC (Advanced High-Speed CMOS) family and is optimized for use in 5V systems.
Key Features:
- Logic Type: Octal Buffer/Line Driver with 3-State Outputs
- Number of Channels: 8
- Output Type: 3-State
- Supply Voltage Range: 4.5V to 5.5V
- Operating Temperature Range: -40°C to 85°C
- Package / Case: SOIC-20
- Mounting Type: Surface Mount
The SN74AHC244DWE4 features two sets of eight buffers with separate output-enable (OE) signals, allowing for flexible control of signal flow. The 3-state outputs can be placed in a high-impedance state, effectively disconnecting the output from the bus, which is a necessary feature in shared-bus configurations.
Applications:
This device is commonly used in a wide range of applications including:
- Bus Interface/Buffering
- Signal Level Translation
- Line Driving for Backplane Distribution
- Memory Address Driving
- Input/Output Port Expansion
The SN74AHC244DWE4 is characterized for operation from -40°C to 85°C, ensuring reliability across a wide range of environmental conditions. The device is available in a compact SOIC-20 package, making it suitable for space-constrained applications.
Quality and Reliability:
Texas Instruments is renowned for its commitment to quality and reliability, and the SN74AHC244DWE4 is no exception. It is designed and manufactured to meet the stringent requirements of the industrial and commercial markets, ensuring performance and durability in the most demanding situations.
