The IRC TaNCap
®
IEEE1284 parallel printer interface
networks are designed for use in printer and other
digital digital interface applications. These highly inte-
grated 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 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 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.
