The TaNCap^™QRC1±84x± is a single package solution

The ±8-pin in QSOP package offers a high level of integration

in a single surface mount device. 43 discrete passive

components are replaced by one IEEE 1±84x± filter network.

designed for the IEEE1±84 enhanced parallel port interface

and other digital interface applications. This highly integrated

TaNCap^™thin film technology network offers four different

functions in a single ±8-pin QSOP package.

The TaNCap series of resistor-capacitor networks are

manufactured using military and space proven tantalum

nitride thin film technology. For high reliability combined with

superior performance.

R1 is a pull-up resistor for, R± is a series termination resistor

and C is a low pass filter capacitor. ESD protection is provided

for each termination line.
