Product Summary

The SN75976A2DLR is a 9-channel differential transceiver. It is offered in two versions. The SN75976A2DLR skew limits of 4 ns for the differential drivers and 5 ns for the differential receivers complies with the recommended skew budget of the Fast-20 SCSI standard for data transfer rates up to 20 million transfers per second. The SN75976A2DLR supports the Fast SCSI skew budget for 10 million transfers per second.
