Product Description
Note: CAMDs P/Active 1284 Parallel Port Termination Network is an upgraded version of the original PRC1284 or IPEC1284 which provides ESD protection, minimized lead inductance and parasitic capacitive effects, and improved crosstalk and filter performance characteristics at high data transmission rates. The PAC1284 is recommended for all new designs.
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.
