SGS Thomson Microelectronics SA12B5, SA16B3, SA16B6 Datasheet
SA12B5
Application SpecificDiscretes
A.S.D.
MAINAPPLICATIONS
Any electronic equipment where suitable bus
termination is required to avoid signal reflections
anddistortions:
PCs
Workstations
High frequencyprocessorboards
Dataline interface
DESCRIPTION
Dedicatedto bus termination,the Schottkyarrays
SA12B5, SA16B3 and SA16B6 minimise stray
emissions from PCB tracks. Theyprovide suitable
termination by avoiding signal reflexions and
distortions.

BENEFITS
Provides impedance matching, and minimizes
distortion.
LowersEMI /RFI radiation.
Eliminates negative voltage : minimizes risk of
latch-upfor sensitiveICs.
Savesvaluable spaceon board.
