Table 26. Switching Characteristics
Notes:
1. Test conditions assume signal transition time of 1V/ns or higher, timing reference levels of VCC(typ.) /2, input pulse levels of
0 to VCC(typ.), and output loading of the specified IOL/IOH and 30 pF load capacitance.
2. tHZOE, tHZCE, tHZBE and tHZWE transitions are measured when the outputs enter a high-impedance state.
3. High-Z and Low-Z parameters are characterized and are not 100% tested.
4. To achieve 55-ns performance, the read access should be CE# controlled. In this case tACE is the critical parameter and tSK is
satisfied when the addresses are stable prior to chip enable going active. For the 70-ns cycle, the addresses must be stable
within 10 ns after the start of the read cycle.
5. The internal write time of the memory is defined by the overlap of WE#, CE#1 = VIL, CE2 = VIH, BHE and/or BLE =VIL. All
signals must be Active to initiate a write and any of these signals can terminate a write by going Inactive. The data input set-
up and hold timing should be referenced to the edge of the signal that terminates write.
