Package

The TRSF3221EIDBR is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package) format, which is designed for compact and efficient mounting on circuit boards.

Pinout

The TRSF3221EIDBR is a dual universal asynchronous receiver-transmitter (UART) device with a pin count of 20. It is designed for level shifting between different voltage levels, commonly used in communication between devices operating at different logic levels (e.g., 3.3V and 5V).
Pin Functions:
- TXD (Transmit Data): Sends data from the device.
- RXD (Receive Data): Receives data to the device.
- GND: Ground connection.
- VCC: Supply voltage.
- A and B pins: Used for level shifting; A pins connect to the higher voltage side while B pins connect to the lower voltage side.
- DIR (Direction Control): Determines the direction of data flow.
- EN (Enable): Activates the level shifter.
- Additional pins for various functions related to fault detection, configuration, and control.
The TRSF3221EIDBR is ideal for applications requiring reliable communication between mixed-voltage systems.
