and other digital interface applications. This highly integrated
鈩?/div>
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 in QSOP package offers a high level of integration
in a single surface mount device. 43 discrete passive
components are replaced by one IEEE 1284x2 filter network.
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.
