TaNCap
Integrated Filter Network
QRC1284x2Series
• Single chip parallel port solution
• Built-in ESD protection into 17 lines
• Proven TaNCap® thin film technology
• Highly Integrated - replaces 43 discretes
• RoHS compliant and Sn/Pb terminations available
The IRC TaNCap® QRC1284x2 is a single package
solution designed for the IEEE1284 enhanced parallel
port interface and other digital interface applications.
This highly integrated TaNCap® thin film technology
network offers four different functions in a single 28-
pin 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® 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.
