CF94395GB - Brand New Texas Instruments IC Chips
-
Description
The CF94395GB is an Enhanced SCSI-2 Controller designed for Fast SCSI-2 transfer rates of up to 10 Mbytes/s in synchronous mode and up to 7 Mbytes/s in the asynchronous mode. It is downward compatible with the Am53C94/96 and incorporates features such as Fast SCSI, programmable Active Negation, a 24-bit transfer counter, and a part-unique ID code containing manufacturer and serial number information.
