Key Featrues
ESD Protection over ±10kV: The LT1180A/LT1181A features robust ESD protection, allowing it to withstand multiple ±10kV strikes. This eliminates the need for additional TransZorbs® on RS232 line pins, reducing component count and cost while enhancing reliability in harsh environments.
Uses Small Capacitors: 0.1µF: By requiring only 0.1µF external capacitors, the LT1180A/LT1181A simplifies board design and reduces space requirements. This feature is particularly beneficial for compact, portable devices where space is at a premium.
120kBaud Operation for RL = 3k, CL = 2500pF: The device supports high-speed data transmission up to 120kBaud even with heavy capacitive loads (2500pF). This ensures reliable communication in applications with long cables or high noise environments, such as industrial systems or modems.
Low Power Consumption: 40mW: With a power consumption of just 40mW, the LT1180A/LT1181A is highly efficient, making it ideal for battery-powered systems like portable computers or handheld terminals, where energy efficiency is critical.
Outputs Withstand ±30V Without Damage: The driver outputs are protected against overload and can withstand short circuits to ground or voltages up to ±30V without damage. This rugged design ensures durability and reliability in demanding applications, such as power supply generators or industrial terminals.
