The SN74LVC244ADBR from Texas Instruments is an octal buffer/line driver from the 74LVC logic family. It is designed for low-voltage applications, operating from 1.65V to 3.6V. The non-inverting buffer features 3-State outputs, allowing for bus-oriented applications. With a robust 24mA output drive capability, it can handle high-capacitance loads and long transmission lines. Packaged in a 20-SSOP, this IC is ideal for 3.3V and lower-voltage systems, including memory interfacing, FPGA connections, and general-purpose signal buffering.
- Low-Voltage Operation (1.65V-3.6V): Perfect for modern 3.3V and 2.5V logic systems, reducing power consumption.
- High Drive Current (24mA): Ensures signal integrity when driving multiple loads or long traces.
- 3-State Outputs: Facilitates bus sharing and multiplexing in complex digital systems.
- Wide Temperature Range (-40°C to 125°C): Suitable for industrial and automotive environments.
3.3V Bus Buffering
Use the SN74LVC244ADBR to buffer address or data lines in 3.3V microcontroller systems. The 24mA drive current ensures clean signals even with high fan-out.
Memory Interfacing
Connect 3.3V SRAM or Flash memory to a processor. The 3-State outputs allow multiple memory banks to share the same data bus.
Level Shifting from 3.3V to 1.8V
While primarily a buffer, it can be used with pull-up resistors to interface 3.3V logic to 1.8V devices, as the outputs are overvoltage tolerant.
Peripheral Driver
Drive multiple peripheral ICs (sensors, ADCs, DACs) from a single processor port. The high drive current prevents signal degradation.
FPGA/CPLD Interface
Buffer signals between an FPGA and external components. The low-voltage operation matches modern FPGA I/O standards.
Telecommunications Equipment
In networking gear, this buffer conditions control and data signals between line cards and backplanes, ensuring reliable operation.
