Vishay Thin Film
25 Mil Pitch, IEEE 1284 Termination Network
Resistor, Capacitor, Diode
FEATURES
• Lead (Pb)-free available
Pb-free
• One sophisticated, integrated Thin Film
Available
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
Uses include ECP/EPP parallel port terminations for PC
peripherals, notebooks, desktops, workstations and servers.
This is a guaranteed stock part.
• Increase board utilization
• Better performance over discretes
