The MC74AC244DWR2G from onsemi is a high-speed dual buffer with non-inverting 3-State outputs. Operating from 2V to 6V, it provides 24mA of drive current per channel, making it versatile for bus-oriented systems. Its 74AC logic family ensures fast propagation delays, while the 20-SOIC package suits space-constrained designs. Typical applications include memory address buffering, signal conditioning, and driving multiple loads in mixed-voltage environments.
- Wide 2V to 6V Supply Range: Simplifies design by supporting both 3.3V and 5V logic levels without extra components.
- High 24mA Output Drive: Enables direct driving of LEDs, relays, or multiple TTL inputs, reducing the need for external drivers.
- 3-State Outputs: Allows multiple devices to share a common bus safely, preventing data corruption.
- High-Speed 74AC Performance: Ensures minimal propagation delay for critical timing applications.
Bus Interfacing in Mixed-Voltage Systems
The 3-State outputs and wide 2V-6V supply range make it ideal for interfacing 3.3V microcontrollers with 5V peripherals, ensuring reliable data transfer without level-shifting circuitry.
High-Speed Signal Buffering
With 74AC family speed and 24mA sink/source capability, it buffers high-frequency clock or data signals, preserving signal integrity over longer PCB traces.
Driving Multiple Loads
Each output can drive up to 24mA, making it suitable for driving multiple TTL inputs or small LED arrays in indicator panels.
Memory Address/Data Bus Expansion
In microprocessor systems, the 3-State outputs allow the buffer to be disabled, enabling multiple memory banks to share the same data bus without contention.
Industrial Control Logic
Operating from -40°C to 85°C, it reliably buffers sensor signals and control logic in industrial automation equipment.
Telecommunications Line Cards
Its high-speed performance and 3-State capability are well-suited for buffering control signals in telecom switching and line interface cards.
