The MC74LCX244DWR2 from onsemi is a dual non-inverting buffer from the 74LCX family, optimized for low-voltage, high-speed applications. Operating from 2V to 3.6V, it features 3-State outputs and 5V tolerant inputs, making it a versatile solution for mixed-voltage systems. With 24mA output drive capability, it can handle demanding bus loads. The 20-SOIC package is suitable for compact PCB designs.
- 5V Tolerant Inputs: Safely interfaces with legacy 5V logic without damage, simplifying mixed-voltage design.
- Low-Voltage Operation (2V-3.6V): Ideal for modern 3.3V and lower power systems, reducing overall power consumption.
- High Drive (24mA): Ensures reliable signal transmission over longer traces and multiple loads.
- 3-State Outputs: Facilitates bus multiplexing and prevents data corruption in shared-line architectures.
3.3V to 5V Level Shifting
With 5V tolerant inputs, the MC74LCX244DWR2 can safely interface 5V logic signals to a 3.3V microcontroller, eliminating the need for external level shifters.
High-Speed Data Bus Buffering
In networking equipment or servers, this buffer isolates the CPU from memory or peripheral buses, reducing parasitic capacitance and maintaining signal quality at 24mA drive.
Low-Power Portable Devices
For battery-powered gadgets, the 74LCX family's low quiescent current extends battery life while providing necessary drive for LCD data lines or sensor interfaces.
Mixed-Voltage Industrial Sensors
Industrial sensors often output 5V signals. This buffer allows a 3.3V PLC or controller to read those signals reliably without damage.
FPGA Configuration Interfacing
When configuring FPGAs from a 3.3V PROM, this buffer ensures clean, high-speed signal propagation to the FPGA's configuration pins.
Memory Module Drivers
In DDR memory modules, this buffer can drive address and control lines, ensuring tight timing and low skew across the module.
