Note: The maximum load on -WAIT# is 1 LSTTL with 50pF total load. All times are in nanoseconds. Dout signifies data provided by the CompactFlash Storage Card or CF+ Card to the system. The WAIT# signal may be ignored if the OE# cycle to cycle time is greater than the Wait Width time. The Max Wait Width time can be determined from the Card Information Structure. The Wait Width time meets the PCMCIA specification of 12ps but is intentionally less in this specification.
