The SN74ALVC244NSR is a dual-channel non-inverting buffer with 3-State outputs, designed for low-voltage (1.65V to 3.6V) applications. It delivers 24mA of drive current, making it suitable for high-speed bus driving and signal conditioning. The 20-SOIC package is ideal for space-efficient PCB layouts. This buffer is commonly used in memory interfaces, peripheral drivers, and level-shifting circuits.
- Low-Voltage Operation (1.65V-3.6V): Perfect for modern low-power processors and FPGAs.
- High Drive Current (24mA): Ensures fast signal transitions and drives capacitive loads effectively.
- 3-State Outputs: Facilitates bus sharing and reduces power consumption when idle.
- Dual-Channel Design: Saves board space by integrating two buffers in one package.
Low-Voltage Bus Interfacing
In 1.8V or 2.5V systems, the SN74ALVC244NSR provides high-speed buffering with 24mA drive, ensuring reliable communication between low-voltage processors and peripherals.
Memory Address Buffering
Use this buffer to drive multiple memory banks. The 3-State outputs allow selective enabling of memory modules, reducing capacitive loading on the address bus.
Level Shifting (1.8V to 3.3V)
When powered at 3.3V, the device can accept 1.8V logic inputs (with proper thresholds) and output 3.3V levels, enabling mixed-voltage system design.
High-Speed Data Paths
With 24mA output current, this buffer can drive high-speed data lines in networking equipment, maintaining signal integrity at frequencies up to 100MHz+.
Port Expansion for Microcontrollers
Expand GPIO capabilities by using the 3-State outputs to multiplex multiple input sources to a single microcontroller pin.
Server and Telecom Backplanes
The low-voltage operation and high drive current make it suitable for buffering control signals in dense backplane architectures.
