Frequently Asked Questions
How many signal lines does the UCC5614PWPG4 terminate?
The UCC5614PWPG4 terminates 9 SCSI signal lines simultaneously, providing complete active termination for a full byte-wide SCSI bus plus one additional line, which aligns with standard narrow SCSI bus configurations requiring proper impedance matching on all data and control lines.
What package does the UCC5614PWPG4 use and what are its key dimensions?
The UCC5614PWPG4 is housed in a 24-pin TSSOP package (JESD-30 code R-PDSO-G24) with a 0.25-inch lead pitch (TSSOP24,.25 equivalence) and a plastic/epoxy body. The thin small-outline profile reduces board height, making it suitable for high-density server and storage PCB designs.
Is the UCC5614PWPG4 RoHS compliant?
Yes, the UCC5614PWPG4 is RoHS compliant with a Pb-free code of 'Yes' and JESD-609 code e4, confirming it meets lead-free and halogen-free environmental standards. Verify compliance documentation with your distributor for specific lot traceability.
What types of SCSI applications is the UCC5614PWPG4 designed for?
The UCC5614PWPG4 is designed for narrow SCSI bus termination in applications including server storage controllers, RAID enclosures, tape backup units, and industrial embedded computers. It ensures signal integrity on SCSI buses operating at standard and fast SCSI transfer rates by providing accurate active termination voltage and impedance.
Does the UCC5614PWPG4 support differential SCSI output?
No, the UCC5614PWPG4 does not support differential output (Differential Output: NO). It is designed for single-ended SCSI bus termination. For differential SCSI or Ultra2/Ultra160 LVD applications, a different terminator IC designed for low-voltage differential signaling would be required.
