STMicroelectronics Interface - Interface - Drivers, Receivers, Transceivers - ST3237EBPR ST3237EBPR

The ST3237EBPR is a ±15kV ESD-protected RS-232 transceiver designed for communication interfaces operating at supply voltages between 3V and 5.5V. It features five drivers and three receivers, supporting data rates of up to 250Kbps in normal operation and 1Mbps in very high-speed operation. The device includes a low-power shutdown mode with a current draw of 1mA when receivers are active, making it suitable for power-sensitive applications. The transceiver is equipped with enhanced ESD protection, rated at ±15kV for the I/O pins using the Human Body Model and ±8kV for contact discharge per IEC 1000-4-2 standards. It operates with a guaranteed slew rate of 6V/µs in normal mode and 24V/µs in high-speed mode, ensuring reliable signal integrity. The ST3237EBPR is available in a compact SSOP-28 package, making it suitable for space-constrained designs.
