Product Description
California Micro Devices聮 Super 1284 Parallel Port Termination Network provides a complete integrated solution for the entire
IEEE 1284 interface in a single QSOP package.
Advanced, enhanced high-speed parallel ports, conforming to the IEEE 1284 standard, are used to provide communications
with external devices such as tape back-up drives, ZIP drives, printers, parallel port SCSI adapters, external LAN adapters, scanners,
video capture, and other PC peripherals. These advanced ports support bi-directional transfers to 2MB/sec. To effectively support
these higher transfer data rates, the IEEE 1284 standard recommends a combined termination, 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 strict filtering on the parallel port. California Micro Devices聮 Super 1284 Parallel Port Termination Network
addresses all of these requirements by providing a seventeen line, IEEE 1284 compliant network in a thin film integrated circuit.
The device provides a complete parallel port termination solution for space critical applications by integrating a total of 43
discrete components. In addition, all I/O pins are ESD protected for contact discharges up to 4KV per the Human Body Model.
However, the output pins of the device which have the highest probability of exposure to ESD pulses are protected to 8KV, HBM,
thereby providing the necessary robustness for the port聮s application environment.
California Micro Devices聮 P/Active technology provides high reliability and low cost through manufacturing efficiency. The resistors
and capacitors are fabricated using proprietary state-of-the-art thin film technology. California Micro Devices聮 solution is silicon-
based and has the same reliability characteristics as today聮s integrated circuits.
