SRM2264L

The SRM2264L is an 8,192 words * 8 bits asynchronous,static,random access memory on a monolithic CMOS chip. SRM2264L's very low standby power requirement makes it ideal for applications requiring non-volatile storage with back-up batteries.

Features of the SRM2264L are:(1)fast access time;(2)low supply current;(3)completely static is no clock required;(4)single power supply is 5V±10%;(5)TTL compatible inputs and outputs;(6)3-state output with wire-OR capability;(7)non-volatile storage with back-up batteries;(8)package is 28-pin DIP(plastic,28-pin SOP (plastic).

The absolute maximum ratings of the SRM2264L can be summarized as:(1):the parameter is supply voltage,the symbol is VDD,the rating is -0.5 to 7.0,the unit is V;(2):the parameter is input voltage,the symbol is VI,the rating is -0.5 to 7.0,the unit is V;(3):the parameter is input/output voltage,the symbol is VI/O,the rating is -0.5 to VDD+0.3,the unit is V;(4):the parameter is power dissipation,the symbol is PD,the rating is 1.0,the unit is W;(5):the parameter is operating temperature,the symbol is Topr,the rating is 0 to 70,the unit is ;(6):the parameter is storage temperature,the symbol is Tstg,the rating is -65 to 150,the unit is ;(7):the parameter is soldering temperature and time,the symbol is Tsol,the rating is 260,10 s(at lead),the unit is .
