2DIB1401F

Overview

Dual-channel digital isolator 2DIB1401F in DSO-8 narrow body package

Infineon’s ISOFACE™ dual-channel digital isolator 2DIB1401F (with 1 forward channel and 1 reverse channel) provides robust isolation for high voltage applications. With a wide supply voltage range, CMOS input thresholds and default output state high, it is the perfect fit for isolated bus communication such as UART/CAN with logic high in idle conditions.
