64MB 72 PIN EDO
DRAM SIMM With 16Mx4 3.3VOLT
ABSOLUTE MAXIMUM RATINGS*
Item
Symbol Rating Unit
Voltage on any pin relative to Vss VIN, VOUT -1 to +7.0 V
Voltage on Vcc supply relative to Vss Vcc -1 to +7.0 V
Storage temperature Tstg -55 to +125 °C
Power dissipation PD 8 W
Short circuit output current IOS 50 mA
Mean time between failure MTBF 50 years
Note:
Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are
exceeded.
Functional operation should be restricted to the conditions as detailed in the operational
sections of this data sheet.
Exposure to absolute maximum rating conditions for intended periods may affect device
reliablilty.
RECOMMENDED OPERATION CONDITIONS (Voltage referenced to Vss, T
A = 0 to 70℃)
