ISO1541
Overview
The ISO1540 and ISO1541 devices are low-power, bidirectional isolators that are compatible with I2C interfaces. These devices have logic input and output buffers that are separated by Texas Instruments Capacitive Isolation technology using a silicon dioxide (SiO2) barrier.
- Isolated bidirectional, I2C compatible, communication
- Supports up to 1-MHz operation
- 3-V to 5.5-V supply range
- Open-drain outputs With 3.5-mA Side 1 and 35- mA Side 2 sink current capability
- -40°C to +125°C operating temperature
- ±50-kV/µs transient immunity (Typical)
- HBM ESD protection of 4 kV on all pins; 8 kV on bus pins
- Safety-related certifications: - 4242-VPK isolation per DIN EN IEC 60747-17 (VDE 0884-17) - 2500-VRMS isolation for 1 minute per UL 1577 - CSA approval per IEC 62368-1 end equipment standard - CQC basic insulation per GB4943.1-2011
