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