概述

Description

ISO7242ADWR is TI’s isolated dual-channel digital isolator in the ISO724x family. It provides galvanic isolation between two power domains (A-side and B-side) and crosses two independent digital signals across the barrier without a direct electrical connection.
Key points
- Dual, uni-directional digital channels across an isolation barrier
- Separate supply rails for each side (A-side and B-side)
- Built-in protections and robust noise and ESD performance
- Small package (variant-dependent) and available in automotive/industrial options with corresponding temperature ratings
- Includes defined default output behavior for fault tolerance
Typical use
- Isolating microcontroller or logic I/O from high-voltage or noisy sections (industrial controls, motor drives, power supplies, sensors)
Note
- ADWR denotes the exact variant (packaging, tape-and-reel options, and temperature grade). For precise electrical specs (propagation delay, capacitance, current, and supply ranges), consult the ISO7242ADWR datasheet and design guides.

Features

Here are the key features of ISO7242ADWR (TI digital isolator family):
- Two isolated digital channels (dual-channel) with galvanic isolation between primary and secondary sides
- Wide input/output supply rails (VDD1 and VDD2) supporting common logic levels (3.3V/5V range)
- Automotive-grade option available (A-side vs. DWR suffix indicates extended temperature and AEC capabilities)
- High-speed digital transfer with low propagation delay and low power consumption
- High common-mode transient immunity (CMTI) for robust noise rejection
- Strong ESD protection and fault-tolerant operation
- Small footprint, package options suitable for surface-mount designs
- RoHS compliant; Tape-and-Reel (WR) packaging option
Note: exact electrical specs (data rate, isolation rating, voltage ranges, temp range) vary by variant. Refer to the datasheet for precise numbers for ISO7242ADWR.

Package

8-pin wide-body SOIC (SOIC‑8). The DWR suffix indicates Tape & Reel packaging.

Pinout

Pin count: 8 pins (8-pin package, e.g., SOIC-8).
Function: ISO7242ADWR is a dual-channel digital isolator. It provides two independent, unidirectional data paths with galvanic isolation between the input side (Vcc1/GND1) and the output side (Vcc2/GND2).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs, manufactures, and sells analog and embedded processing ICs and related technologies. It is one of the world’s largest semiconductor manufacturers, with a global presence and headquarters in Dallas, Texas.

Application

ISO7242ADWR is a dual-channel digital isolator. Typical applications include:
- Galvanic isolation between microcontroller/logic and high-voltage/noisy industrial or power electronics
- Isolated I/O interfaces and communications (SPI/I2C/UART) across barriers
- Gate-drive/interface signals for motor drives and power converters
- Automotive safety and body/electronic control units
- PLCs and industrial process control
- Medical instrumentation and data acquisition systems requiring isolation

Equivalent

To give exact equivalents, I need specs: supply (5V/3.3V), isolation voltage, speed, package, and whether 3-state outputs are needed. For general substitutes, two-channel digital isolators often used are Analog Devices ADuM1250/ADuM1251 or Broadcom/Avago ACPL-7721/7723, but please verify timing and pinout.
