The 74LCX240MSA from ON Semiconductor is a high-performance, low-voltage octal buffer and line driver designed to operate with a 3.3 V power supply while still being 5V tolerant at input and output ports. This makes it ideal for interfacing between systems operating at different voltage levels.

Key Features

• 5V Tolerant Inputs and Outputs: The 74LCX240MSA's inputs and outputs can tolerate 5V, allowing it to be used in mixed voltage applications without the need for level shifters.
• Low Voltage Operation: Optimized to operate at 3.3V, this device offers low power consumption while maintaining high-speed operation.
• High-Speed Performance: It features propagation delays and output transition times which are significantly lower than those of typical 5V devices.
• Power-Off High Impedance Inputs and Outputs: This ensures no excess current is drawn if the power is off, making it suitable for power-sensitive applications.
• Support for Live Insertion and Withdrawal: The device can be inserted or removed without powering down the system, thanks to its bus-hold circuitry which prevents floating inputs and eliminates the need for pull-up/down resistors.
• Multiple Package Options: Available in a variety of packages, the 74LCX240MSA offers flexibility for different design and space requirements.

Applications

The 74LCX240MSA is versatile and can be used in a wide array of applications, including:

• Interface translation
• Backplane driving
• Clock driving
• Bus isolation
• Memory driving
