VSSX1284
Vishay Thin Film
25 Mil Pitch, IEEE 1284 Termination Network
Resistor, Capacitor, Diode
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).
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.
FEATURES
• Lead (Pb)-free standard
• One sophisticated, integrated Thin Film _RoHS
technology solution
COMPLIANT
• 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
