| TaNCap(R) IEEE 1284 Integrated Filter Network QRC1284x2TM Series * Single chip parallel port solution * Built-in ESD protection into 17 lines * Proven TaNCap(R) thin film technology * Highly Integrated - replaces 43 discretes * RoHS compliant and Sn/Pb terminations available The IRC TaNCap(R) QRC1284x2 is a single package solution designed for the IEEE1284 enhanced parallel port interface and other digital interface applications. This highly integrated TaNCap(R) thin film technology network offers four different functions in a single 28pin QSOP package. R1 is a pull-up resistor for, R2 is a series termination resistor and C is a low pass filter capacitor. ESD protection is provided for each termination line. The 28-pin QSOP package offers a high level of integration in a single surface mount device. 43 discrete passive components are replaced by one IEEE1284x2 filter network. The TaNCap(R) 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.
