Product Summary

The MCZ33298EGR2 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 MCZ33298EGR2 include the control of solenoids, relays, lamps, small DC motors, and other moderate current loads (1.0 – 3.0A).
