bit serial input control. The 33291L is a versatile circuit designed for
automotive applications, but is well suited for other environments. The
33291L incorporates SMARTMOS technology, with CMOS logic,
bipolar/MOS analog circuitry, and DMOS power MOSFETs. The
33291L interfaces directly with a microcontroller to control various
inductive or incandescent loads.
