The SN74LS244DWR2 is an octal buffer/driver designed for high-performance memory interface applications. It is a non-inverting buffer with 3-state outputs, making it suitable for driving bus lines and memory address lines. The device provides high current drive capability while maintaining low power consumption.
Applications
- Memory address decoding
- Data bus buffering
- Line driving
- Clock distribution
Features
- Octal buffer/driver configuration
- Non-inverting outputs
- 3-State outputs
- High output drive capability (15mA IOL, -12mA IOH)
- Low power consumption
- Schottky clamped inputs for improved switching performance
- Wide operating voltage range: 4.75V to 5.25V
Benefits
- High drive capability allows it to drive highly capacitive loads and long bus lines.
- 3-state outputs allow multiple devices to share a common bus without contention.
- Low power consumption reduces overall system power requirements.
- Schottky clamped inputs minimize ringing and improve noise immunity.
- Wide operating voltage range provides flexibility in system design.
The SN74LS244DWR2 is characterized for operation from 0°C to 70°C. This device has two separate enable inputs (1G and 2G), each controlling four buffers. This allows for selective enabling of different sections of the device.
Package Information: The SN74LS244DWR2 is available in a SOIC (Small Outline Integrated Circuit) package. The 'DWR2' suffix indicates tape and reel packaging.
Operating Considerations: To ensure stable operation, proper decoupling capacitors should be used near the power supply pins. Unused inputs should be tied to VCC or ground to prevent floating input conditions.
