LTC1334ISW#TR - High-Efficiency, Low-Power RS232/RS485 Multiprotocol Transceiver

The LTC1334ISW#TR from Linear Technology is a versatile multiprotocol transceiver designed to cater to the demanding requirements of mixed RS232 and RS485 data communications. This integrated circuit provides a seamless interface between different protocol standards, making it an ideal choice for systems that require reliable data exchange across various platforms.

Featuring a wide supply voltage range of 4.5V to 5.5V, the LTC1334ISW#TR is capable of operating in environments with fluctuating power supplies, ensuring consistent performance. The device is optimized for low power consumption, drawing a minimal 250µA of supply current when in full operation, and only 10µA in shutdown mode, thus extending the life of battery-powered applications.

The transceiver includes two RS232 drivers and two receivers, alongside an RS485 driver and receiver, allowing for half-duplex communication. The RS232 drivers maintain a 250kbps data rate, while the RS485 drivers support a higher data rate of 2.5Mbps, making the LTC1334ISW#TR suitable for high-speed data transfer applications.

One of the standout features of this product is its enhanced electrostatic discharge (ESD) protection. The RS232 pins can withstand ESD strikes of up to ±10kV, ensuring robustness and reliability in harsh industrial environments. The device also includes a charge pump circuit that generates the necessary RS232 voltage levels from a single 5V supply, eliminating the need for additional power sources.

The LTC1334ISW#TR comes in a 28-lead SOIC wide package, which is designed for surface-mount technology (SMT), providing a compact footprint for space-constrained applications. The operating temperature range of the device spans from -40°C to 85°C, which allows its use in a wide range of industrial and commercial temperature environments.

Whether it's for industrial control systems, point-of-sale terminals, or data communication equipment, the LTC1334ISW#TR offers a reliable and efficient solution for multiprotocol data transfer, ensuring seamless integration and communication between different devices.
