The MC74LCX244DWG is a high-performance non-inverting buffer from onsemi's 74LCX family. It features two 4-bit buffer sections with 3-State outputs, enabling efficient bus management. Operating from 2V to 5.5V, it supports both 3.3V and 5V logic levels, while delivering 24mA of drive current. The 20-SOIC package is ideal for space-constrained designs. Typical applications include memory buffering, peripheral driving, and level translation in industrial and automotive systems.
- Wide 2V to 5.5V Supply Range: Compatible with both 3.3V and 5V systems, simplifying mixed-voltage design.
- High 24mA Output Drive: Ensures reliable signal transmission to high-capacitance loads and multiple inputs.
- 3-State Outputs: Enables bus sharing and isolation, preventing data contention.
- Extended Temperature Range (-55°C to 125°C): Suitable for harsh automotive and industrial environments.
Bus Interfacing and Isolation
The 3-State outputs and high-impedance mode allow the MC74LCX244DWG to isolate bus segments when disabled, preventing data contention in multi-master systems.
Signal Buffering for High-Capacitance Loads
With 24mA drive capability, this buffer can drive long PCB traces or multiple IC inputs, maintaining signal integrity in memory address and data lines.
Level Shifting Between 3.3V and 5V Logic
Operating from 2V to 5.5V, it can translate signals between 3.3V microcontrollers and 5V legacy peripherals, simplifying mixed-voltage designs.
Driving LED Arrays and Displays
The high sink current (24mA) makes it suitable for directly driving LED segments or small indicator lamps in control panels.
Industrial Control Input/Output Modules
In PLCs and industrial controllers, the buffer provides robust signal conditioning for sensor inputs and actuator outputs, withstanding noisy environments.
Automotive ECU Signal Distribution
With a wide temperature range (-55°C to 125°C), it reliably distributes control signals in engine management and body control modules.
