The SN74LVT244BNSR is a dual non-inverting buffer from Texas Instruments, part of the 74LVT low-voltage BiCMOS family. It operates from 2.7V to 3.6V, making it ideal for modern 3.3V logic systems. With 3-State outputs and high drive capability (32mA source, 64mA sink), it excels in bus interface and signal buffering applications. The 20-pin SOIC package offers a compact footprint for space-constrained designs.
- High Sink Current (64mA): Drives heavy loads like multiple logic inputs or LEDs without additional components.
- Low-Voltage Operation (2.7V-3.6V): Compatible with 3.3V microcontrollers and FPGAs, reducing power consumption.
- 3-State Outputs: Allows multiple devices to share a bus safely.
- BiCMOS Technology: Combines low power of CMOS with high speed of bipolar for optimal performance.
3.3V Bus Interfacing
Use the SN74LVT244BNSR to buffer data lines in 3.3V FPGA or ASIC designs. The high sink current (64mA) ensures reliable signal transmission on heavily loaded buses.
Level Shifting (3.3V to 5V Tolerant)
While operating at 3.3V, the 74LVT family can interface with 5V TTL logic on the input side, making it useful for mixed-voltage systems.
High-Drive LED Driving
The 64mA sink capability allows direct driving of high-current LEDs or optocouplers in industrial control panels.
Memory Interface Buffering
For DDR or SDRAM controllers, this buffer provides the necessary drive strength and 3-State isolation for address/control signals.
Telecom Line Card Buffering
In networking equipment, it buffers control signals between line cards and backplanes, ensuring signal integrity over long traces.
Battery-Powered Portable Devices
With a low 2.7V minimum supply, it is suitable for battery-operated devices where power efficiency is critical.
