Notes:
1. Customers requiring delivery in Tape and Reel should add the character “T” to the end of the part number. Example: GS8640FZ36T-8IVT.
2. The speed column indicates the latency (ns) in Flow Through mode.
3. TA = C = Commercial Temperature Range. TA = I = Industrial Temperature Range.
4. PQ = Pre-Qualification.
5. GSI offers other versions this type of device in many different configurations and with a variety of different features, only some of which are
covered in this data sheet. See the GSI Technology web site (www.gsitechnology.com) for a complete listing of current offerings
