Thin Film on Silicon 2CTA AC Terminator x 18
Features
■RoHS compliant*
■18 RC terminators tied to a common
node
■Stable thin-film-on-silicon technology
■Ultra-miniature packages to JEDEC
standards
Applications
■High-speed bus termination
■Low power consumption
■Ideal for space-constrained applications
General Information
The AC Terminator is used to provide termination for clock
and data lines where transmission line effects would
otherwise cause wave reflections or signal ringing. These
Silicon-based, Tantalum-Nitride resistors and capacitors
feature excellent stability, temperature coefficients and
tracking performance. This product series conforms to
JEDEC standards.
