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.
