Re Note that the UCN5812AF (dual in-line package) current outputs also allow them to be used in other peripheral power driver applications. They are improved versions of the original UCN5812A/EP. The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With a 5 V supply, they will operate to at least 3.3 MHz. At 12 V, higher speeds are...
