The 4 channels are split 3\/1: three channels forward (A,B,C side 1 to side 2) and one channel reverse (D side 2 to side 1). The -F suffix specifies the channel direction (3F\/1R). The isolation uses silicon dioxide (SiO2) dielectric between two transformer coils, manufactured with TI's planar transformer technology. Unlike optocouplers, the digital isolator uses RF coupling: the input signal modulates a 300MHz carrier that is magnetically coupled across the isolation barrier, then demodulated on the output side. This provides: (1) Much higher speed (150Mbps vs 10Mbps for optocouplers); (2) No LED degradation (optocouplers age due to LED CTR degradation); (3) Lower power (3mA per channel vs 5-15mA for optocouplers); (4) Wider temperature range (-55C to +125C). The M suffix specifies 5000Vrms isolation (vs D suffix for 2500Vrms). The propagation delay is 10ns typical with 2ns channel-to-channel matching. The default output state is LOW when input is unpowered (failsafe). The -DWR suffix specifies SOIC-16W, tape-and-reel. Applications include: SPI\/I2C isolation for ADCs, motor drive signal isolation, and industrial communication interfaces.","pin_description":"
