概述

Description

ISO 7240 is the international family of standards for fire detection and alarm systems. It defines the requirements for the design, performance, installation, testing, and interoperability of sensors, controllers, annunciators, and communication networks used to detect a fire and raise an alarm, as well as integration with other building systems. The suite covers general requirements, control and indicating equipment, installation and use, data communication networks, and related topics. Compliance is demonstrated via third‑party certification to the relevant parts (for example, ISO 7240‑1 for general requirements, ISO 7240‑2 for control/indicating equipment, ISO 7240‑5 for data communication). Regional standards exist as equivalents (e.g., EN 54 in Europe, NFPA 72 in the US).
Regarding “ISO7240CFQDWRQ1”: this appears to be a product or document code rather than a standard. If you meant a specific device, provide the manufacturer or link, and I can check its ISO 7240 conformity or applicable datasheet details.

Features

Here are the typical features of the ISO7240CFQDWRQ1 (I2C digital isolator, 1-channel):
- 1-channel bidirectional isolator for I2C-bus (SDA/SCL)
- Reinforced isolation between sides: VDD1 and VDD2
- Isolation rating: commonly 2.5 kV RMS (reinforced)
- Separate supply rails: VDD1 and VDD2, both 2.7–5.5 V
- I2C compatibility up to 400 kHz (Fast mode) and SMBus
- Automatic direction sensing with fast data transfer across the isolation barrier
- Low power consumption and compact 8-pin QFN package (FQDWRQ1)
- Operating temperature typically -40°C to +125°C
- ESD protection on I/O pins
- RoHS-compliant and suitable for harsh environments
Note: exact specs (e.g., isolation rating, delay, current) can vary by member of the ISO7240 family and package variant. Please refer to the specific datasheet for precise numbers.

Package

8-pin QFN package (QFN-8).

Pinout

Pin count: 8 pins (8-pin package).
Function: ISO7240CFQDWRQ1 is a dual-channel isolated digital isolator. It provides two independent data paths across a galvanic isolation barrier (with separate supply rails on each side) to transfer logic signals between the primary and isolated sides.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: TI is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital ICs and related electronics components.

Application

Application areas of ISO7240CFQDWRQ1:
- Industrial automation and process control (galvanic isolation for sensors/actuators)
- Medical instrumentation (patient-safety isolation)
- Automotive electronics (isolated control/gateway interfaces)
- Power electronics and motor-drive systems (isolated control/data links)
- Data acquisition and instrumentation (isolated sensors and front-ends)
- Isolated communications interfaces (SPI/I2C/UART and GPIO isolation)

Equivalent

Common equivalents for the ISO7240C (2-channel digital isolator) are:
- Analog Devices ADuM1250/1251/1252 (iCoupler digital isolators)
- Silicon Labs Si86xx family (e.g., Si8620/8621)
Ensure matching channel count, Vcc, and isolation rating; use TI’s cross-reference to confirm exact substitutes.
