The 74LVC240ADB is a high-performance, low-voltage Octal Inverting Buffer/Line Driver with 3-state outputs, designed to operate from 1.2V to 3.6V. Manufactured by NXP Semiconductors, this device is part of the LVC family, which stands for Low-Voltage CMOS. It is optimized for use in high-speed signaling applications and is compatible with 5V I/O systems.
Key Features
- Power Supply: Operates across a wide voltage range from 1.2V to 3.6V, making it suitable for battery-powered and low-power systems.
- High Speed: Possesses a 5V tolerant I/O for interfacing with higher voltage logic levels, with a propagation delay (t<sub>pd) of only 3.7ns at 3.3V.
- Drive Capability: Capable of driving up to 50mA at the output, allowing for direct drive of LEDs or other high-current loads.
- 3-State Outputs: Features 3-state outputs to enable connection to a bus or data lines where multiple drivers can be connected.
- Low Power Consumption: The device has a reduced power consumption, especially in standby mode, due to the low quiescent current.
- Bus Hold: Inputs are equipped with bus-hold circuitry, ensuring that floating inputs will not result in undefined operation.
Applications
The 74LVC240ADB is ideal for a variety of applications where buffer or line driving with inverting outputs is required. This includes:
- Memory address drivers
- Data transmission lines
- Control bus drivers
- Microprocessor or microcontroller bus systems
