HY64LD16162M Series
7
Revision 1.7
March. 2002
Notes :
1. Read Cycle occurs whenever a high on the /WE and /OE is low, while /UB and/or /LB and /CS1 and CS2 are in active status.
2. /OE = V
IL
3. tCHZ, tBHZ and tOHZ are defined as the time at which the outputs achieve the high impedance state and tOLZ,tBLZ and tCLZ
are defined as the time at which the outputs achieve the low impedance state.
These are not referenced to output voltage levels.
4. /CS1 in high for the standby, low for active.
/UB and /LB in high for the standby, low for active.
