### **Descriptions:**
- The ISL8323IB is designed for high-speed bidirectional data communication on multipoint bus transmission lines (RS-485/RS-422).
- It features fail-safe circuitry to ensure a logic-high receiver output when inputs are open, shorted, or terminated but not driven.
- The device is optimized for low power consumption while maintaining robust performance in industrial and communication applications.
### **Features:**
- **High-Speed Operation:** Supports data rates up to 20Mbps.
- **Wide Supply Range:** Operates from 3.0V to 5.5V, making it compatible with 3.3V and 5V systems.
- **Low Power Consumption:** 1.5mA (max) in shutdown mode.
- **Enhanced ESD Protection:** ±15kV HBM protection on bus pins.
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.
- **3-State Driver and Receiver Outputs:** Allows bus sharing in multidrop applications.
- **Industrial Temperature Range:** -40°C to +85°C operation.
- **Available in SOIC and QSOP Packages:** Compact footprint for space-constrained designs.
The ISL8323IB is commonly used in industrial automation, motor control, and long-distance communication systems requiring robust RS-485/RS-422 interfaces.
