Key Features
- Dual-channel reinforced digital isolation with up to 100 Mbps data rate for high-speed signal transmission across isolation barriers
- Ultra-low propagation delay under 10 ns enables real-time control in motor drives and industrial communication interfaces
- 8-pin SOIC package with 5 kVrms isolation rating simplifies board layout while meeting IEC 61010 safety requirements
Applications
The ISO6721FBDR is designed for isolating digital signals in industrial motor drives, PLC I/O modules, and RS-485/RS-232 communication interfaces where ground potential differences or transient voltages must be blocked. Its 2-channel architecture and high 100 Mbps data rate make it suitable for fast encoder feedback lines, gate driver signal paths, and isolated SPI bus designs in inverter and servo controller applications. The reinforced isolation rating also qualifies it for medical equipment and energy metering systems requiring strict patient or operator protection per IEC standards.

Frequently Asked Questions
What is the maximum data rate and isolation voltage of the ISO6721FBDR?
The ISO6721FBDR supports data rates up to 100 Mbps and provides reinforced isolation rated at 5 kVrms, allowing it to block high-voltage transients in industrial and motor-drive environments. The propagation delay is under 10 ns, making it suitable for time-critical signal paths in servo systems and high-speed communication interfaces.
How does the ISO6721FBDR compare to single-channel isolators for a dual RS-485 transceiver design?
The ISO6721FBDR integrates 2 isolation channels in a single 8-pin SOIC package, replacing two discrete single-channel isolators and reducing board area by up to 50% compared to using separate SO-6 or SO-8 single-channel devices. Both channels are independently controlled, supporting simultaneous TX and RX signal isolation for a full-duplex RS-485 interface in one component.
What supply voltage range does the ISO6721FBDR accept on each side of the isolation barrier?
The ISO6721FBDR accepts supply voltages from 2.25 V to 5.5 V on both the input and output sides independently, enabling direct interfacing between 3.3 V digital logic and 5 V industrial I/O without level-shifting circuitry. This wide range also accommodates systems powered from 3.3 V microcontrollers alongside 5 V field-side peripherals across a reinforced isolation barrier.
Which safety certifications apply to the ISO6721FBDR and in which regulated industries can it be used?
The ISO6721FBDR meets IEC 61010-1 and IEC 60950-1 reinforced isolation requirements with a 5 kVrms withstand rating, making it usable in industrial automation, medical equipment, and energy metering systems. Its 2-channel design with 8-pin SOIC footprint and JEDEC e4 lead-free compliance supports designs targeting CE marking and UL recognition in safety-critical applications.
