Working Principles

The PI74ALVTC16245AE utilizes a combination of MOSFETs and CMOS technology to achieve voltage-level translation. It employs a bidirectional buffer design, allowing data to flow in both directions between the A-side and B-side pins. The direction of data flow is controlled by the OE pin.

When the OE pin is low, the device is enabled, and the input signals on the A-side are translated to the corresponding voltage levels on the B-side. Conversely, when the OE pin is high, the device is disabled, and the data flow is blocked.

Detailed Application Field Plans

The PI74ALVTC16245AE is commonly used in various applications, including:

1. Communication Systems: Facilitates signal translation between different voltage domains in communication interfaces such as UART, SPI, and I2C.
