ST3232E
Overview
The ST3232E is a 3V to 5.5V powered EIA/TIA-232 and V.28/V.24 communication interface with low power requirements and high ESD protection. It features two receivers and two drivers, making it a standard solution for full-duplex serial communication in embedded systems.
Why Choose This Part
The device features integrated ESD protection up to plus or minus 15 kV (Human Body Model) and plus or minus 8 kV (IEC 1000-4-2 contact discharge), reducing the need for external protection components. It is highly efficient with a typical supply current of only 0.3mA and guarantees data rates up to 250kbps across the full temperature range.
Applications
Key Specifications
Getting Started
When designing with the ST3232E, ensure four 0.1 uF charge pump capacitors are placed as close to the IC pins as possible for stable voltage doubling and inversion. The device is logic-level compatible with both 3.3V and 5V CMOS/TTL microcontrollers, allowing it to interface directly with UART pins without level shifters.
