Descripción general

Description

ISO7740DW is a dual-channel digital isolator in the ISO7740 family. It provides galvanic isolation between two voltage domains to transfer digital signals across an isolation barrier. The device typically includes two data channels (and often an optional enable/reference), with independent supply rails (VCCA and VCCB), built-in undervoltage lockout and fault protection, and a compact DW package. Applications: isolating microcontrollers from high-voltage or noisy circuitry such as motor drivers, sensors, or isolated communication interfaces. For exact specs— isolation rating, data rate, supply ranges, and pinout—consult the specific ISO7740DW datasheet from the manufacturer.

Features

Assuming you mean Renesas/Intersil ISO7740DW digital isolator, its key features are:
- 1-channel, unidirectional digital isolator (data from side 1 to side 2)
- Reinforced isolation between input and output (high Viso)
- Independent supply rails on both sides (Vcc1 and Vcc2); supports common logic levels (3.3 V / 5 V)
- TTL/CMOS-compatible inputs and outputs
- Enable/disable control for on/off data transfer
- Wide operating temperature range (typical -40°C to +125°C)
- RoHS-compliant package with DW suffix (8-pin small-outline style)
- Suitable for isolated interfaces (I2C/SPI, serial buses, sensor interfaces, microcontroller isolation)
Note: exact electrical specs (isolation voltage, propagation delay, CMTI, currents) vary by variant and package. Refer to the official datasheet for precise numbers and verification with your application requirements.

Package

8-pin wide-body SOIC package (DW).

Pinout

Pin count: 8 pins.
Function: ISO7740DW is a single-channel, unidirectional digital isolator (iCoupler) with separate input and output supplies (VDD1/VDD2 and GND1/GND2); it transfers a logic signal across a galvanic isolation barrier.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: An American multinational semiconductor company that designs, manufactures, and sells analog and mixed-signal integrated circuits, microcontrollers, processors, sensors, and related electronic components worldwide.

Application

ISO7740DW is a dual-channel isolated I2C digital isolator. Typical applications:
- Isolating I2C data/clock between microcontrollers and remote peripherals in noisy or high-voltage environments
- Industrial automation, motor drives, and power electronics
- Automotive sensors and ECUs
- Smart metering and energy management
- Medical instrumentation
- Data acquisition systems

Equivalent

Cross-ref depends on specs. ISO7740DW is TI’s 4‑channel digital isolator. Please share your isolation voltage, data rate, channel count, and package to give precise equivalents (e.g., matches from Analog Devices, Renesas, or Broadcom).
