TYPICAL COMMON ANODE APPLICATIONS
A quad junction common anode design in a SC-74
package protects four separate lines using only one package.
This adds flexibility and creativity to PCB design especially
when board space is at a premium. A simplified example of
MMQA/SZMMQA Series Device applications is illustrated
below.
