Mingjiada Supply Original TI ISO7221CDR 25Mbps Dual Channel Digital Isolators

Shenzhen Mingjiada Electronics Co., Ltd.: Professional Supply Original TI ISO7221CDR Dual-Channel Digital Isolator, Enabling Safe Signal Transmission in Industry

In industrial automation, medical equipment, communication systems and new energy applications are increasingly sophisticated today, safe and reliable signal isolation is the core element to ensure the stable operation of the system. As a reliable supply chain partner of electronic components, Mingjiaoda Electronics has been supplying original (TI) ISO7221CDR dual-channel digital isolators for a long time.

The TI ISO7221CDR product details are shown below:

Part Number: ISO7221CDR

Package: SOIC-8

Type: Digital Isolators

Product Details: ISO7221CDR——Dual-Channel, 1/1, 25Mbps Digital Isolators.

ISO7221CDR is a high-performance, dual-channel digital capacitive isolator from Texas Instruments (TI). ISO7221CDR uses TI's advanced capacitive isolation technology, between the input and output circuits to build a strong electrical isolation barrier, effectively blocking high voltage, eliminating ground loop noise, to prevent surge damage to sensitive circuits, to ensure data integrity and system security.

ISO7221CDR Key Specifications
Channel Configuration: Dual channel (2 independent isolated channels).
Channel Orientation: Multiple configurations available (e.g. 1 forward/1 reverse, 2 forward, etc.), ISO7221CDR common suffixes represent specific orientations (please specify the model you need).
Data Rate: Up to 150 Mbps (typical) for high speed signal transmission.
Isolation Levels:
Isolation Voltage (VISO): 2500 Vrms (compliant with UL 1577)
Operating Voltage (VIOWM): 566 Vpeak
Surge Voltage (VIOSM): 4000 Vpk
Transient Immunity (CMTI): 25 kV/µs (min.) for effective rejection of common mode noise.
Supply Voltage:
Input Side (VCC1): 3.3V or 5V
Output Side (VCC2): 3.3V or 5V (both voltages can be selected independently)
Propagation Delay: Extremely low and well-matched (11ns typical) to ensure signal timing accuracy.
Power Consumption: Very low power consumption per channel (1.7mA @ 1 Mbps, 5V typical), energy efficient.
Default Output State: Supports active-high or active-low configurations.
Operating temperature range: -40°C to +125°C for harsh industrial environments.
Package: SOIC-8 (D) package, RoHS compliant for easy soldering and integration.

ISO7221CDR Core Benefits and Key Features
Powerful Electrical Isolation: The ISO7221CDR provides isolation protection up to 2500Vrms, which is a critical barrier to protect personnel and equipment.
High Speed Signal Transmission Capability: Supports data rates up to 150 Mbps for isolation of high speed digital communication interfaces (e.g. SPI, I2C, RS-485/422, digital I/O).
Superior immunity: Extremely high common mode transient immunity (CMTI) of 25 kV/µs ensures stable and reliable signal transmission in noisy industrial environments. Choosing ISO7221CDR means greater system robustness.
Wide Supply Voltage Range and Independence: Both sides of the power supply (3.3V or 5V) can work independently, making it easy to connect systems with different voltage domains.
Low Power and Low Latency: The ISO7221CDR provides high-performance isolation while maintaining low power consumption and low propagation latency in the nanosecond range, optimising system power efficiency and responsiveness.
Wide Temperature Operating Range: Industrial-grade temperature range of -40°C to +125°C for harsh environments.
High Reliability: TI's stringent quality control and proven capacitive isolation technology ensure the long life and high reliability of the ISO7221CDR.
