  • VREF (Pin 39): Voltage Reference for Output Enable

Functional Features

• High-speed operation: The SN74LVTH16374ZRDR can operate at frequencies up to 200MHz, making it suitable for high-performance digital systems.
• Logic level shifting: It allows seamless interfacing between devices operating at different voltage levels, ensuring proper signal transfer.
• 3-state outputs: The 3-state outputs enable multiple devices to share a common bus without interfering with each other.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data transfer in digital systems. - Logic level shifting capability facilitates compatibility between devices with different voltage requirements. - 3-state outputs allow for bus sharing and reduce the number of required pins.

Disadvantages: - Limited supply voltage range restricts its use in systems with different voltage levels. - Propagation delay time may introduce timing issues in certain applications.

Working Principles

The SN74LVTH16374ZRDR operates by receiving data inputs on the D0-D15 pins. The clock pulse (CP) triggers the flip-flop, capturing the data and storing it in the internal memory. The stored data is then available on the Q0-Q15 output pins. The Output Enable (OE) pin controls the activation of the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The SN74LVTH16374ZRDR is commonly used in various digital systems where logic level shifting is required. Some application fields include:

1. Microcontrollers and microprocessors: Facilitating communication between devices operating at different voltage levels.
2. Communication systems: Enabling signal translation between different voltage domains in networking equipment.
3. Industrial automation: Interfacing between sensors, actuators, and control systems with varying voltage requirements.
4. Automotive electronics: Supporting communication between different subsystems in vehicles.
