| VSSX1284 Vishay Thin Film 25 Mil Pitch, IEEE 1284 Termination Network Resistor, Capacitor, Diode FEATURES * Lead (Pb)-free standard * One sophisticated, technology solution integrated Thin Film RoHS COMPLIANT Product is pictured larger than actual size to show detail * Up-graded IEEE 1284 parallel port termination, pull-up with the addition of diodes for filtering on the parallel port * Standard QSOP package (28 pins) - JEDEC mo-137AF * 17 terminating lines * Reduces total cost * Increase board utilization * Better performance over discretes Vishay has upgraded the standard IEEE 1284 Thin Film technology Network, incorporating diodes for protecting the inputs/outputs from electro-static discharge (ESD). The sophisticated circuit is housed in a standard QSOP, 28-pin package. Uses include ECP/EPP parallel port terminations for PC peripherals, notebooks, desktops, workstations and servers. This is a guaranteed stock part.
