ISO1540 - Low-Power Bidirectional I2C Isolators

Description

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.

Features

  • 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 (VD.
