LTC1384CSW - RS232 Transceiver with Integrated Charge Pump

The LTC1384CSW from Linear Technology is a robust RS232 transceiver that features an integrated charge pump circuitry, designed to provide seamless communication for serial data transmission. This product is specifically engineered to facilitate bidirectional communication in applications that require full-duplex RS232 connectivity.

The LTC1384CSW comes in a 20-pin narrow SOIC package, making it compact and suitable for space-constrained applications. It operates over a wide supply voltage range of 4.5V to 5.5V, which allows it to be used in various system designs without the need for additional voltage regulation components. The device is capable of generating RS232 voltage levels from a single 5V supply due to its onboard charge pump circuitry, which can create the necessary ±10V RS232 voltage levels from the single supply voltage.

One of the key features of the LTC1384CSW is its low power consumption. The device includes a power-down feature that reduces the supply current to a mere 10µA, making it an excellent choice for battery-powered or power-sensitive applications. This is particularly important in portable devices where power efficiency is crucial.

The transceiver supports data rates up to 120kbps, providing a balance between speed and reliability for data communication. It is equipped with 0.1µF external capacitors for the charge pump, which minimizes the number of external components required and simplifies the design process.

With its robust electrostatic discharge (ESD) protection, the LTC1384CSW ensures reliable operation even in harsh environments. It can withstand ESD events up to ±10kV, safeguarding the device against unexpected electrical discharges that can occur during installation or operation.

In summary, the LTC1384CSW from Linear Technology is a highly reliable and efficient RS232 transceiver suitable for a wide range of applications, from industrial control systems to portable consumer electronics. Its integrated charge pump, low power consumption, and ESD protection make it a versatile and durable choice for designers looking to implement RS232 communication in their projects.
