SC−74 Quad Monolithic
Common Anode
Transient Voltage Suppressors
for ESD Protection
http://onsemi.com
This quad monolithic silicon voltage suppressor is designed for
applications requiring transient overvoltage protection capability. It is
intended for use in voltage and ESD sensitive equipment such as
computers, printers, business machines, communication systems,
medical equipment, and other applications. Its quad junction common
anode design protects four separate lines using only one package.
These devices are ideal for situations where board space is at a
premium.
