4DIR1421HA

Quad-channel digital isolator 4DIR1421HA in DSO-16 wide-body package

The 4DIR1421HA (with 3 forward channels) is AEC-Q100 qualified and provides robust reinforced isolation for high-voltage automotive applications. Four data channels allow for simplified and high-power density designs and improve system efficiency with low power consumption. With a wide supply voltage range, active-low output enable, and default high output state, it is a perfect fit for SPI communication interface where reinforced isolation is required.
