ST3232BDR Description

Short technical summary and product information.

The STMicroelectronics ST3232BDR is a 3V powered EIA/TIA-232 and V.28/V.24 communication interface device. It features low power requirements and high data-rate capabilities, making it suitable for battery-powered and handheld equipment.

 

This transceiver operates from 3V to 5.5V supplies and requires only four small 0.1 µF external capacitors for operation. It boasts a minimum guaranteed data rate of 250 kbps and a maximum of 400 kbps, along with a minimum slew rate of 6 V/µs. The device includes two receivers and two drivers, meeting EIA/TIA-232 specifications down to 3V.

 

The ST3232BDR is available in an SO16 package, designed for surface mount applications. Its typical supply current is only 300 µA, contributing to its low-power characteristics. Typical applications include notebooks, subnotebooks, palmtop computers, and other portable electronic devices requiring reliable serial communication.

 

This component is ideal for designs where power efficiency and reliable RS-232 communication are critical. Its compact SO16 package facilitates integration into space-constrained applications.
