Product Overview: LT1180ACSW#PBF

The LT1180ACSW#PBF is a high-quality low-power 5V RS232 dual driver/receiver from Linear Technology, which is designed to conform to the RS232 and V.28 specifications while operating with a single 5V power supply. This integrated circuit features a proprietary low dropout transmitter output stage, which enables true RS232 performance from a 5V supply using a dual charge pump.

The charge pump requires only four small 0.1µF external capacitors for operation from a 5V supply. The LT1180ACSW#PBF has been engineered to minimize the supply current when it is not driving a load, making it an excellent choice for power-sensitive applications. It boasts a typical supply current of 250µA, which further reduces to 1µA when the device is placed into its shutdown mode, thereby conserving power in battery-operated systems.

Featuring two drivers and two receivers, this product is capable of operating at data rates up to 120 kbps, making it suitable for various communication applications. The drivers maintain a ±5V output signal level, ensuring reliable data transmission even over long cable runs or in electrically noisy environments.

The LT1180ACSW#PBF is packaged in a 16-pin narrow SO package, offering a compact footprint for designs where space is at a premium. Its robust design includes over-temperature and over-current protection, enhancing its reliability and longevity in demanding applications. The device's receivers can handle up to ±30V input levels, and the driver outputs can be short-circuited to ground or to ±30V without damage.

Overall, the LT1180ACSW#PBF is an excellent choice for designers seeking a reliable and power-efficient RS232 interface solution. Its combination of low-power operation, high data rate capability, and robust protection features make it a versatile component for a wide range of communication applications, from portable devices to industrial control systems.
