TITRS3386EIPWR
Overview
The TRS3386EIPWR is a flexible RS-232 transceiver featuring three drivers and two receivers, designed for high-performance serial communication at data rates up to 250kbps. It includes a dedicated VL pin that allows the logic-side interface to operate as low as 2.5V, ensuring compatibility with modern low-voltage microcontrollers. This part also features enhanced ESD protection on the RS-232 pins to improve system reliability in harsh environments.
Why Choose This Part
The integrated VL pin is a significant advantage for engineers, eliminating the need for additional level-shifting ICs when interfacing with low-voltage logic. Additionally, the device is optimized for low power with a typical supply current of 0.3mA and features robust ESD protection on all RS-232 bus pins.
Applications
Key Specifications
Getting Started
To implement this part, place 0.1uF charge pump capacitors as close to the VCC and V+ pins as possible to ensure stable voltage doubling. Ensure the VL pin is tied to the I/O voltage of your microcontroller to set the logic threshold correctly. For prototyping, the 20-TSSOP package can be used with a standard SMT breakout board and a logic analyzer to verify the 250kbps signal integrity.
