The SN74LVC244APW is a non-inverting octal buffer from Texas Instruments, part of the 74LVC logic family. It features 16 channels (2 x 8-bit) with 3-State outputs, providing high-density buffering. Operating from a 1.65V to 3.6V supply, it can source and sink 24mA, making it suitable for low-voltage applications. The 20-TSSOP package is compact for space-constrained PCBs. Typical applications include level shifting, bus buffering, and signal conditioning in portable and automotive electronics.
- Low-Voltage Operation (1.65V-3.6V): Compatible with modern low-power microcontrollers and SoCs.
- High Channel Count (16): Reduces component count in wide-bus applications.
- Wide Temperature Range (-40°C to 125°C): Suitable for automotive and industrial environments.
- 3-State Outputs: Allows for bus sharing and isolation.
3.3V to 1.8V Level Shifting
The SN74LVC244APW can shift signals from a 3.3V microcontroller down to a 1.8V peripheral. Its low-voltage operation and 3-State outputs make it ideal for mixed-voltage SoC designs.
High-Density Bus Buffering
With 16 channels in a compact TSSOP package, this buffer can isolate a 16-bit data bus from a processor. The 24mA drive current ensures reliable communication with multiple memory chips.
Portable Device Signal Conditioning
In battery-powered devices, the low 1.65V minimum supply allows operation from a single-cell battery. The buffer can drive LEDs or interface with low-voltage sensors, extending battery life.
FPGA Configuration Interfacing
When configuring an FPGA from a 3.3V flash memory, this buffer can cleanly drive the configuration pins. The 3-State outputs allow the FPGA to take control of the bus after configuration.
Automotive Sensor Interfaces
With a temperature range up to 125°C, this buffer is suitable for under-hood automotive applications. It can buffer signals from temperature or pressure sensors to the ECU.
Server and Networking Equipment
In servers, this buffer can drive control signals to multiple DIMM slots. The low-voltage operation reduces power consumption, which is critical in high-density data centers.
