manufacturer: description:the ds1642 is in the write mode whenever we and ce are in their active state. the start of a write is referenced to the latter occurring transition of we or ce . the addresses must be held valid throughout the cycle. ce or we must return inactive for a minimum of twr prior to the initiation of another read or write cycle. data in must be valid tds prior to the end of write and remain valid for tdh afterward. in a typical application, the oe signal will be high during a write cycle. however, oe can be active provided that care is taken with the data bus to avoid bus contention. if oe is low prior to we transitioning low the data bus can become active with read data defined by the address inputs. a low transition on we will then disable the outputs twez after we goes active. |
