Product Description

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 also 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. CAMDs P/Active 1284 Parallel Port Termination Network addresses all of these requirements by providing a nine line, IEEE 1284 compliant network, in a thin film integrated circuit. Two of these devices replace up to 54 discrete components and provide a complete parallel port termination solution for spacecritical applications.
