Key Features
- 3-State Outputs: The device features four output enables (1OE, 2OE, 3OE, and 4OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
- Input Tolerance: Inputs can be driven from either 3.3 V or 5 V devices, making it suitable for mixed voltage environments.
- Schmitt-Trigger Action: All inputs have Schmitt-trigger action, which makes the circuit tolerant of slower input rise and fall times and enhances noise immunity.
- Partial Power Down Capability: The device is fully specified for partial power down applications using IOFF circuitry, which disables the output and prevents backflow current when powered down.
- Low Power Dissipation: The device has low power dissipation considerations, making it energy-efficient.
Applications
The 74LVC16244ADGG,112 is versatile and can be used in a variety of applications across different industries, including:
- Automotive: Suitable for automotive electronics due to its robustness and compliance with automotive standards.
- Industrial: Used in industrial control systems, motor drives, and other industrial automation applications.
- Consumer Electronics: Found in consumer devices that require reliable and efficient digital logic operations.
- Computing and Networking: Used in computing and networking equipment for data transmission and signal buffering.
