- In order to initialize the circuit, CE and OEL/RFSH should be kept
- AC characteristics shall be tested with tT = 5 ns.
- AC characteristics are measured at the following condition (see figure
- Address is latched at the negative edge of CE.
- Measured with a load equivalent to 2TTL + 100 pF.
- Data for the lower byte (I/O1 to I/O8) is latched at the positive edge
