ISO1540 Datasheet Low-power Bidirectional I2c Isolators

Manufacturer: Texas Instruments

Overview: ISO1540, ISO1541 SLLSEB6F – JULY 2012 – REVISED DECEMBER 2022 ISO154x Low-Power Bidirectional I2C Isolators.

General 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.

When used with isolated power supplies, these devices block high voltages, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.

Key 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.
