ISO1540DR

The safety and regulatory approvals mentioned for the ISO1540 and ISO1541 isolators include: - Isolated bidirectional, I2C compatible communications - 4000-V PK isolation per DIN EN 60747-5-2 (VDE 0884 Part 2) (Pending) - 2500-V RMS isolation for 1 minute per UL 1577 (Approved) - CSA Component Acceptance Notice 5A - -40°C to 125°C Operating Temperature - IEC 60950-1 and IEC 61010-1 End Equipment Standards (Pending) - ±50kV/µs Transient Immunity (Typical) - HBM ESD Protection of 4kV on All Pins; 8kV on Bus Pins ISO1540 and ISO1541 isolators have specific safety and regulatory approvals in place to ensure their proper functioning and compliance with industry standards.

Isolated bidirectional communication in the ISO1540 and ISO1541 devices is achieved by offsetting the Side 1 Low-Level Output Voltage to a value greater than the Side 1 High-Level Input Voltage, thus preventing an internal logic latch that would otherwise occur with standard digital isolators .
