The SN74LVC2244ADBR is a dual 4-bit buffer from Texas Instruments, part of the 74LVC logic family. It provides 8 non-inverting channels with 3-State outputs, delivering 12mA of output current per channel. Operating from a low 1.65V to 3.6V supply, it is perfect for modern low-voltage systems, including 3.3V and 1.8V applications. This buffer is widely used for memory interfacing, FPGA signal conditioning, and portable device power management. The 20-SSOP package offers a compact footprint for space-constrained PCBs. Its operating temperature range of -40°C to 85°C covers most commercial and industrial applications.
- Low 1.65V to 3.6V Supply Range: Ideal for battery-powered and low-voltage digital systems.
- 12mA Output Current: Ensures fast switching and reliable signal drive for high-speed buses.
- Dual 4-bit Configuration: Provides independent enable controls for flexible design.
- 3-State Outputs: Facilitates bus sharing and prevents data conflicts in multi-master systems.
Low-Voltage Bus Interfacing
Use the SN74LVC2244ADBR to buffer data lines in 3.3V or 1.8V systems. Its 1.65V to 3.6V range ensures compatibility with modern low-voltage processors and FPGAs.
Signal Buffering for High-Speed Memory
Buffer address and control signals to DDR or SRAM modules. The 12mA output current provides fast edge rates, maintaining signal integrity at high frequencies.
Level Shifting in Mixed-Voltage Designs
Interface 1.8V logic to 3.3V peripherals. The 74LVC family accepts inputs up to 5.5V (with VCC at 3.3V), allowing safe level translation.
Portable Device Power Management
