6) If the CE low transition occurs simultaneously with or later than the WE low transition in write cycle
7) If the CE high transition occurs prior to or simultaneously with the WE high transition, the output
8) If WE is low or the WE low transition occurs prior to or simultaneously with the CE low transition,
9) Each DS1386 is marked with a four-digit date code AABB. AA designates the year of manufacture.
10) All voltages are referenced to ground.
11) Applies to both interrupt pins when the alarms are set to pulse.
12) Interrupt output occurs within 100ns on the alarm condition existing.
13) Both INTA and INTB (INTB) are open-drain outputs.
14) Real-Time Clock modules (DIP) can be successfully processed through conventional wave-soldering
