The MC74VHC244DWR2G from onsemi is a high-speed, non-inverting octal buffer designed for 2V to 5.5V operation. This 74VHC family device features 3-State outputs, enabling efficient bus-oriented applications. With 8mA of output drive capability and a wide temperature range, it is ideal for buffering signals in mixed-voltage digital systems, industrial controls, and memory interfacing. The 20-SOIC package offers a compact solution for space-constrained PCBs.
- Wide 2V to 5.5V Supply Range: Compatible with both 3.3V and 5V logic systems, simplifying mixed-voltage design.
- High-Speed 74VHC Technology: Provides fast propagation delays while maintaining low power consumption, ideal for high-frequency signal buffering.
- 3-State Outputs: Allows multiple devices to share a common bus without signal contention, enhancing system flexibility.
- Extended Temperature Range (-55°C to 125°C): Suitable for automotive and industrial applications where environmental extremes are common.
Bus Interfacing and Isolation
Use the MC74VHC244DWR2G to buffer address or data lines between a microcontroller and memory or peripherals. The 3-State outputs allow multiple devices to share the bus without contention, controlled by the output enable pins.
Signal Buffering for High-Speed CMOS
With its 74VHC family heritage, this buffer provides high-speed signal propagation while maintaining low power consumption. It is ideal for buffering clock signals or high-frequency data lines where signal integrity is critical.
Level Shifting Between 3.3V and 5V Systems
Operating from 2V to 5.5V, this buffer can be powered at 3.3V to interface with 5V logic inputs, or vice versa. It provides a simple solution for mixed-voltage systems without additional level-shifting circuitry.
Driving Multiple Loads
Each output can source or sink 8mA, making it suitable for driving multiple TTL inputs or light LED indicators. The non-inverting nature simplifies logic design.
Industrial Control Input/Output Modules
In industrial PLCs and control systems, this buffer can condition and isolate signals from sensors or actuators. Its wide temperature range (-55°C to 125°C) ensures reliable operation in harsh environments.
Memory Address Decoding
Use the buffer to strengthen address signals before they are distributed to multiple memory chips. The 3-State outputs allow for easy bus sharing in multi-bank memory configurations.
