LTC1383CS#PBF: RS232 Transceiver with Integrated Charge Pump

The LTC1383CS#PBF is a versatile RS232 transceiver integrated circuit designed by Linear Technology, which is now part of Analog Devices. This product is specifically engineered to facilitate serial communication in applications where space and power efficiency are critical. The LTC1383CS#PBF stands out for its low-power operation and its ability to generate the necessary RS232 voltage levels from a single 3V to 5.5V supply, thanks to its built-in charge pump circuitry.

The device features a dual charge pump that allows for RS232 performance at data rates up to 120kbps while maintaining a low supply current. This makes it an ideal solution for battery-powered, portable devices such as PDAs, laptops, and other mobile computing devices that require reliable data communication with minimal power consumption.

The LTC1383CS#PBF is housed in a compact, 16-pin narrow SOIC package, which is well-suited for space-constrained applications. It supports multiple drivers and receivers, typically including three drivers and five receivers, providing a robust interface for serial data exchange. The transceiver's receivers can remain active even when the device is powered down, enabling the monitoring of serial ports in a low-power state.

Protection features are also a key aspect of the LTC1383CS#PBF, as it includes over-temperature and over-voltage protection to ensure device and system integrity under harsh operating conditions. The transceiver is also equipped with a shutdown feature that reduces the supply current to a mere 1µA, further enhancing its power-saving capabilities.

Overall, the LTC1383CS#PBF is a highly reliable and efficient solution for RS232 communication. It is designed to meet the stringent requirements of modern portable electronics, providing both the performance and durability needed for a wide range of applications. Whether it’s for mobile devices, GPS systems, or any other serial communication needs, the LTC1383CS#PBF is an excellent choice for designers looking for a high-quality, low-power RS232 transceiver.
