Product Summary
The MC33298DW is a smart eight output low side power switch. It is a versatile device incorporating an 8-bit serial-in shift register to control an 8-bit parallel output latch providing control of eight independent ON/OFF output switches. Applications of the MC33298DW include the control of solenoids, relays, lamps, small DC motors, and other moderate current loads (1.0 – 3.0A). The MC33298DW interfaces directly with a microcontroller to control various inductive or incandescent loads. Input control is fast. Data rates are guaranteed to 2.0 MHz but the device is capable of rates to 8.5 MHz @ 25℃.
