Wide Decoder 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, there derived from benchmark timing patterns. The following
guidelines relflect 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.

)
and output delay (one of 4 modes), as listed on page 2-70.
