Longline Switching Characteristic Guidelines
Testing of the switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are
100% functionally tested. Since many internal timing parameters cannot be measured directly, they are derived from
benchmark timing patterns. The following guidelines reflect worst-case values over the recommended operating
conditions. For more detailed, more precise, and more up-to-date timing information, use the values provided by the
XACT timing calculator and used in the simulator.
Note:
Description
TBUF driving a Longline
TS
I to Longline, while TS is Low; i.e., buffer is constantly active
TS going Low to Longline going from floating High or Low to
active Low or High
TS going High to TBUF going inactive, not driving Longline
I

TBUF
Die-size-dependent parameters are based upon XC5210 characterization. Production specifications will vary with array
size.
