Product Description
The Texas Instruments ISO7240CFDW is a high-performance 4-channel digital isolator IC engineered for demanding electronic and industrial applications. This isolator enables capacitive-based galvanic isolation, allowing data transmission between circuit sections without electrical connectivity, enhancing both safety and signal integrity. With a maximum data rate of 150 Mbps, it is ideal for fast digital interfaces in automation, instrumentation, industrial control, and power systems. Its advanced design supports both forward and reverse channel operation and ensures high electromagnetic immunity.
Utilizing a 2.5 kVrms isolation voltage and supporting both 3.3V and 5V supply voltages, the device adapts well to standard logic families and multi-voltage systems. The ISO7240CFDW comes in a compact 16-pin SOIC package and is surface-mountable, making it suitable for automated production environments and PCB layouts where space is critical.
With a propagation delay of just 42 ns and a rise time of 2 ns, this digital isolator allows precise high-speed data transfer with minimal distortion or timing loss. The low input current of 10 μA helps conserve power in complex multi-device circuits, while the rated power dissipation of 220 mW ensures reliable performance even under full load.
Compliant with insulation standards including VDE 4000 VPK per DIN V VDE V 0884-10, UL 1577, CSA Notice 5A, and IEC 60950-1, the ISO7240CFDW is suitable for use in safety-critical and industrial-grade systems. It is designed for applications such as PLCs, sensor interfaces, industrial networking, medical electronics, and high-voltage motor control circuits.
Industrial use cases include automation equipment, laboratory instruments, embedded controller systems, and signal isolation in power distribution modules.
