ST3232BDR Description

Short technical summary and product information.

The STMicroelectronics ST3232BDR is a multichannel RS-232 line transceiver designed for efficient serial communication. It features two drivers and two receivers, operating from a single 3.0V to 5.5V supply voltage.

 

This transceiver meets the requirements of TIA/EIA-232-F and ITU V.28 standards, providing a robust electrical interface. It supports data signaling rates up to 250kbit/s, making it suitable for various communication applications. The device operates within a temperature range of -40°C to 85°C.

 

Packaged in a 16-SOIC (0.154", 3.90mm Width) surface-mount package, the ST3232BDR is designed for ease of integration into electronic designs. It requires external capacitors for its charge-pump circuit, enabling low-power operation.

 

Key electrical characteristics include a supply voltage range of 3V to 5.5V and a typical operating supply current of 0.3mA. The transceiver supports full duplex communication and offers receiver hysteresis of 300mV.
