The LT1180CS is a significant offering from Linear Technology, a company renowned for its high-performance analog integrated circuits. The LT1180CS is a low-power 5V dual RS232 driver/receiver that stands out in the market for its innovative features and reliable performance. Designed to conform to the EIA/TIA-232E and V.28/V.24 specifications, the LT1180CS is perfect for applications that require efficient serial communication with minimal power consumption.
This versatile IC is characterized by its low supply current, which is typically 250µA, making it an excellent choice for battery-powered and portable devices. Moreover, the LT1180CS features a shutdown mode that reduces the supply current to a mere 1µA, further extending the battery life of the devices it's used in. The drivers and receivers of the LT1180CS can operate effectively over a ±30V input range, providing a robust interface in environments subject to high noise levels or voltage spikes.
The LT1180CS includes two drivers and two receivers. The driver output levels are capable of swinging ±10V, and they are protected against overload, ensuring the IC's longevity and reliability. The receivers can handle up to ±30V and are equipped with a 0.3V hysteresis to increase noise immunity, a feature that is particularly useful in industrial settings with electrical interference.
One of the key benefits of the LT1180CS is its ease of use. It requires only four external 0.1µF capacitors for the charge pump circuit, which generates the necessary RS232 voltage levels from a single 5V supply. This simplifies the design and reduces the overall component count and board space.
The LT1180CS is available in a 16-pin narrow SO package, making it a compact solution suitable for space-constrained applications. Whether it's for use in portable computing devices, networking equipment, or industrial machinery, the LT1180CS is a reliable and efficient solution for serial communication needs.
