AC Terminator Series
Today’s high speed digital circuits demand top performance while maintaining low power dissipation. IRC’s
TaNCap® AC termination networks are designed to meet the needs of the digital circuit designer by blocking DC
current flow into the terminating resistor during the steady-state portion of the digital signal while passing current
into the tantalum nitride terminating resistor during the presence of signal edges and transients.
The SOIC, QSOP, and TSSOP packages offer a high level of integration in today’s most popular surface mount
configurations. One AC Termination network replaces up to 36 discrete components.
The TaNCap® series of resistor-capacitor networks are manufactured using IRC’s military and space proven
tantalum nitride thin film technology. For high reliability combined with superior performance, use IRC TaNCap®
AC termination networks for your high speed, digital circuit applications.
