TaNCap® QSOP IEEE 1284 Filter Network QRC1284 Series • Improves signal quality • Reduces unwanted RF emissions • Built-in ESD protection into 17 lines • Proven TaNSil® Thin Film Technology • Highly Integrated - replaces up to 27 Discretes The QSOP package offers a high level of integration in a single surface mount device. Up to 27 discrete passive components are replaced by one IEEE1284 filter network. The IRC TaNCap® IEEE1284 parallel printer interface networks are designed for use in printer and other digital digital interface applications. These highly integrated TaNSil™ thin film technology network offer three different functions in a single 24-pin QSOP package. R1 is a pull-up resistor for use with open collector and open drain drivers. R2 is a series termination resistor and C acts as a low pass filter. 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 IEEE1284 filter networks for your most demanding designs.
