It is a general-purpose part designed for breaking ground loops and providing safety isolation in industrial, instrumentation, and power-conversion interfaces where signal integrity matters at data rates up to 25Mbps. The six channels are configured as three inputs on side 1 and three inputs on side 2, giving you a balanced, bidirectional isolation path in a single 20-pin SSOP or QSOP footprint. ## 25Mbps data rate and timing margins for your bus Rated at 25Mbps, this isolator comfortably handles SPI clocks up to 25 MHz, UART data at common baud rates, and general-purpose parallel or serial control signals. The 50ns maximum propagation delay in either direction (tpLH / tpHL) and 6ns maximum pulse-width distortion mean the timing skew across channels is tight enough for most synchronous interfaces without extra delay compensation. ## Industrial temperature range and common-mode transient immunity The minimum common-mode transient immunity of 15kV/µs means the isolation barrier holds up against fast voltage transients from switching power stages or inductive loads — a common failure point for optocoupler-based designs in noisy environments. ## Supply range and 5V compatibility The supply voltage range of 3V to 5.5V on both sides lets you run the isolator from a single 3.3V rail, a 5V rail, or mix them — for example, a 3.3V microcontroller on side 1 talking to a 5V peripheral on side 2. No external level shifters are needed. The part does not provide isolated power; each side needs its own local supply and decoupling. ## Package and footprint: 20-SSOP / 20-QSOP Housed in a 20-SSOP body (3.90mm width, 0.154\" pitch) with surface-mount leads, the ADUM7643CRQZ-RL7 also maps to the supplier device package 20-QSOP. The 1.27mm lead pitch is standard and easy to route on two-layer boards. ## Lifecycle and compliance The ROHS3 compliance is fully certified, no exemptions expiring.","metaTitle":"ADUM7643CRQZ-RL7 iCoupler Digital Isolator, 6-Ch, 25Mbps","metaDescription":"ADUM7643CRQZ-RL7: 6-channel digital isolator, 25Mbps data rate, 1000Vrms isolation, -40°C to 105°C.
