The MC74VHC240 is a high-speed dual inverting buffer from onsemi, designed for general-purpose logic buffering in 2V to 5.5V systems. It features 3-State outputs that enable bus-oriented applications, with 8mA of drive current per channel. Housed in a compact 20-TSSOP package, this IC is ideal for signal conditioning, bus isolation, and driving capacitive loads in computing, industrial, and consumer electronics.
- Wide 2V to 5.5V Supply Range: Ensures compatibility with both 3.3V and 5V logic systems, simplifying power design.
- High-Speed 74VHC Technology: Provides fast propagation delays, suitable for high-frequency signal buffering.
- 3-State Outputs: Enables bus multiplexing and isolation, preventing data bus contention.
- 8mA Output Drive: Can directly drive LEDs and other low-power loads, reducing component count.
- Industrial Temperature Range: Operates reliably from -40°C to 85°C for demanding environments.
Bus Interfacing and Isolation
The 3-State outputs allow multiple devices to share a common data bus. The MC74VHC240 can isolate the bus when disabled, preventing data contention and signal corruption in mixed-signal environments.
Signal Buffering for High-Speed Digital Lines
With its high-speed 74VHC technology, this buffer can drive long PCB traces and capacitive loads without significant signal degradation, ensuring signal integrity in high-frequency applications.
Level Shifting Between 3.3V and 5V Systems
Operating from 2V to 5.5V, it can be powered at 3.3V to accept 3.3V logic and drive 5V-tolerant inputs, or vice versa, simplifying mixed-voltage system design.
Driving LED Arrays and Displays
The 8mA source and sink capability is sufficient to directly drive low-current LEDs, eliminating the need for external transistor drivers in indicator and display applications.
Memory Address and Control Signal Buffering
In microprocessor systems, this buffer can fan out address and control signals to multiple memory banks, improving drive strength and reducing loading on the CPU.
Industrial Control Logic
Its wide operating temperature range (-40°C to 85°C) and robust CMOS technology make it suitable for industrial PLCs and control systems that require reliable logic buffering.
