ST3232BDR Low Power 2 Driver/2 Receiver Transceiver

The ST3232BDR is a robust transceiver module from STMicroelectronics, designed to ensure reliable communication and interface in serial data transfer protocols. This device is part of the ST3232B series, which are 3V-powered EIA/TIA-232 and V.28/V.24 communication interfaces with low power requirements and a wide supply voltage range.

Featuring two drivers and two receivers, the ST3232BDR offers a compact and efficient solution for bidirectional communication. It is particularly suitable for applications where power consumption is critical, as it operates in a supply voltage range of 3.0V to 5.5V, ensuring compatibility with a variety of logic families.

One of the key advantages of the ST3232BDR is its low-power consumption. It operates with a no-load supply current that is less than 1µA, making it an excellent choice for battery-operated and portable devices. Despite its low power consumption, the transceiver is capable of maintaining a data rate of up to 400 kbps, providing a balance between energy efficiency and performance.

The ST3232BDR also includes a dual charge pump circuit that allows the transceiver to maintain proper RS-232 voltage levels, even at 3V supply, without the need for additional external components. This feature simplifies design and reduces board space requirements.

Protection is a critical aspect of any transceiver, and the ST3232BDR does not disappoint. It incorporates ESD protection up to 15 kV, ensuring the device's resilience against electrostatic discharges and enhancing its reliability in harsh environments. Additionally, the transceiver is equipped with a low-power shutdown mode, which further reduces power consumption when the device is not actively transmitting or receiving data.

STMicroelectronics has packaged the ST3232BDR in a space-saving 16-pin SOIC package, making it suitable for applications where board space is at a premium. Whether it's for mobile phones, modems, or other serial communication systems, the ST3232BDR provides a dependable, low-power solution that designers can trust.
