The ISO7221CD Dual-Channel Digital Isolator from Texas Instruments delivers reliable galvanic isolation across two separate channels, engineered for high-speed digital communication and rugged industrial environments. Boasting a robust silicon dioxide isolation barrier, this device effectively separates input and output circuitry, ensuring protection against high voltages, noise, and ground loops, while supporting data integrity, operational safety, and a streamlined PCB layout.

Why Buy the ISO7221CD?

You want the ISO7221CD because it strikes an ideal balance between performance and safety. Designed for demanding applications, it provides dependable isolation of up to 2500 Vrms (and surge ratings of up to 4000 Vpk), paired with low latency and tight skew characteristics. Whether you're working in automation, data acquisition, or peripheral interfacing, this isolator ensures smooth, interference-free operation, even in tough conditions.

Product Highlights – What Makes It Stand Out

Dual unidirectional channels for flexible signal routing and PCB layout optimization
High isolation voltage: 2500 Vrms (application-level), with transients up to 4000 Vpk
Fast data transfer: Capable of up to 25 Mbps signaling, with low propagation delay (~36 ns typical)
Precision timing: Minimal pulse-width distortion (~2 ns max) and output skew (channel-to-channel ~1 ns) ensure synchronized signal integrity
Broad voltage compatibility: Operates across 2.8 V to 5.5 V supply ranges, supporting diverse system needs
Robust electrical immunity: High common-mode transient immunity (~25 kV/µs) and ESD protection (~4 kV) for resilience in noisy environments
Wide thermal performance: Operational from –40 °C to +125 °C to suit industrial-grade requirements
Long-term reliability: Designed for approximately a 28‑year lifespan at rated voltage, underlining its stability and longevity.
