The SN74LV244ARKSR is a dual-channel, non-inverting buffer from Texas Instruments, part of the 74LV logic family. It operates over a wide supply voltage range of 2V to 5.5V, making it versatile for various system designs. Each of its two channels can source or sink 16mA, providing robust drive capability. The 3-State outputs allow for bus-oriented applications, enabling multiple devices to share a common data path. Housed in a compact 20-VFQFN package, this buffer is suitable for signal buffering, bus interfacing, and level-shifting applications in industrial and consumer electronics.
- Wide 2V to 5.5V Supply Range: Compatible with both 3.3V and 5V logic systems, simplifying mixed-voltage design.
- High 16mA Output Drive: Ensures reliable signal transmission even with high capacitive loads.
- 3-State Outputs: Enables bus multiplexing and isolation, preventing data bus contention.
- Extended Temperature Range (-40°C to 125°C): Suitable for harsh industrial environments.
Bus Interfacing and Isolation
The 3-State outputs allow the SN74LV244ARKSR to be used for bus isolation, preventing data contention when multiple devices share a common data bus.
Signal Buffering for High-Fanout Systems
With 16mA output drive capability, this buffer can drive multiple loads, ensuring signal integrity in high-fanout digital systems.
Level Shifting Between 3.3V and 5V Systems
Its wide 2V to 5.5V supply range makes it ideal for interfacing 3.3V microcontrollers with 5V peripherals, simplifying mixed-voltage designs.
Driving LED Displays and Indicators
The high current sink capability (16mA) makes it suitable for directly driving LEDs in indicator and display applications.
Industrial Control Input/Output Modules
In industrial PLCs and control systems, this buffer provides robust signal conditioning for sensor inputs and actuator outputs, operating reliably across -40°C to 125°C.
Memory Address and Data Line Buffering
It can buffer address and data lines in memory systems, reducing capacitive loading on the memory controller and improving signal timing.
