TYPICAL COMMON ANODE APPLICATIONS
A quad junction common anode design in a SC-59 pack-
age protects four separate lines using only one package.
This adds flexibility and creativity to PCB design especially
when board space is at a premium. Two simplified examples
of MMQA5V6T1 and MMQA20VT1 applications are illus-
trated below.
