The SN74LVC244AN is a dual 4-bit non-inverting buffer from the 74LVC family, designed for low-voltage (1.65V to 3.6V) applications. It features 3-state outputs for bus-oriented systems, with each channel capable of sourcing or sinking 24mA. Housed in a 20-pin DIP package, it is ideal for through-hole prototyping and industrial control systems requiring robust signal buffering.
- Low-Voltage Operation (1.65V to 3.6V): Perfect for modern 1.8V, 2.5V, and 3.3V logic systems, reducing power consumption.
- 3-State Outputs: Enables bus multiplexing and prevents bus contention in multi-device systems.
- High Output Drive (24mA): Can drive heavy capacitive loads and multiple inputs, improving signal integrity.
- Wide Temperature Range (-40°C to 125°C): Suitable for industrial and automotive environments.
Bus Interfacing for Microcontrollers
Use the SN74LVC244AN to buffer address or data lines between a 3.3V microcontroller and memory or peripherals. The 3-state outputs allow multiple devices to share the same bus without contention.
Memory Address Driving
Drive SRAM or Flash memory address lines with this buffer. Its 24mA output current can handle the capacitive load of multiple memory chips, ensuring fast and reliable access times.
Level Shifting from 1.8V to 3.3V
With a supply of 3.3V, inputs can accept 1.8V logic levels, making it a simple unidirectional level shifter for interfacing low-voltage sensors or FPGAs.
Peripheral Expansion for 3.3V Systems
Buffer GPIO signals from a 3.3V processor to drive multiple LEDs, relays, or other loads, protecting the processor from excessive current draw.
Test and Measurement Equipment
Use it to isolate and buffer signals in test fixtures, providing a clean, buffered copy of the signal to multiple measurement instruments.
Industrial Control Inputs
Buffer signals from industrial sensors or switches to a PLC or controller. The 3-state outputs enable multiplexing of multiple input groups onto a single data bus.
