Functional Features

• Bidirectional level shifting between a 3.3V bus and a 5V bus.
• Incorporates register functionality for data storage.
• 3-state outputs allow multiple devices to share the same bus without interference.
• Inputs are 5V tolerant, allowing direct connection to a 5V bus.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - Low-voltage operation reduces power consumption. - 5V tolerant inputs provide compatibility with legacy systems. - 3-state outputs enable bus sharing without conflicts.

Disadvantages: - Limited operating frequency of 200MHz may not be suitable for high-speed applications. - Only supports bidirectional level shifting between 3.3V and 5V buses.

Working Principles

The SN74LVTH652DWRG4 operates by receiving data from either Bus A or Bus B and storing it in an internal register. The direction of data flow is controlled by the DIR pin. When DIR is high, data flows from Bus A to Bus B, and when DIR is low, data flows from Bus B to Bus A.

The OEAB pin enables or disables the output buffers for both Bus A and Bus B. When OEAB is low, the outputs are enabled, allowing data to be transmitted. Conversely, when OEAB is high, the outputs are disabled, effectively isolating the IC from the bus.

The OE pin allows individual control over the output buffers for each bus. When OEA is low, the outputs for Bus A are enabled, and when OEB is low, the outputs for Bus B are enabled.

Detailed Application Field Plans

The SN74LVTH652DWRG4 is commonly used in various applications that require bidirectional level shifting between a 3.3V bus and a 5V bus, along with register functionality. Some potential application fields include:

1. Microcontroller Interfacing: The IC can be used to interface a microcontroller operating at 3.3V with peripheral devices operating at 5V.
