MICROPOWER RRO Operational Amplifier with Shutdown
Features
· Stable resistor-capacitor network
· 9 terminating lines/package
· Saves board space, reduces assembly cost,
simplifies routing
· ESD protected
· Miniature QSOP package
Product Description
Advanced, high-speed parallel ports, conforming to the
IEEE 1284 standard, are used to provide communica-
tions with external devices such as tape back-up drives,
ZIP drives, printers, parallel port SCSI adapters, external
LAN adapters, scanners, and other PC peripherals.
These advanced ports support bi-directional transfers to
2MB/sec and above. To support these data rates, the
IEEE 1284 standard recommends a combined termina-
tion, pull-up filter network between the driver/receiver
and the cable at both ends of the parallel port interface.
In addition, government EMC compatibility requirements
impose the need to include a filter on the parallel port.
Applications
· ECP/EPP Parallel Port termination
· EMI/RFI Filter
· Notebook and Desktop computers
· Engineering Workstations and Servers
C1210600
SCHEMATIC CONFIGURATION
The PRC1284 addresses all of these requirements by
providing a nine line, IEEE 1284 compliant network in a
thin film integrated circuit. Two of these networks replace
54 discrete components and provide a complete parallel
port termination.
CAMD's PRC1284 Parallel Port Termination Network is a
convenient single function which includes pull-up, series
termination, and an EMI filter capacitor. The resistors
and capacitors are fabricated using proprietary state-of-
the-art thin film technology.
