Product Summary

The SN75976A2DGGRG4 is an 9 channel differential transceiver. The A version offers improved switching performance, a smaller package, and higher ESD protection. The SN75976A2DGGRG4 is offered in two versions. The 976A2 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 976A1 supports the Fast SCSI skew budget for 10 million transfers per second.
