Standby: 15µA (max.) n Extended operating temperature range: 0°C to 70°C for -S series, -25°C to 85°C for -SI series, -40°C to 85°C for -SU series. n Full static operation, no clock or refreshing required n All inputs and outputs are directly TTL compatible n Common I/O using three-state output n Data retention voltage: 2.0V (min.) n Available in 28-pin SOP and TSOP (forward type) packages 8K X 8 BIT CMOS SRAM General Description The A623308 is a low operating current 65,536-bit static random access memory organized as 8,192 words by 8 bits and operates on a single 5V power supply. Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures. Minimum standby power is drawn by this device when CE is at a high level, independent of the other input levels. Data retention is guaranteed at a power supply voltage as low as 2.0V.

A Write occurs during the overlap (tWP) of a low CE and a low W E . tWR is measured from the earliest of CE or W E going high to the end of the Write cycle. If the CE low transition occurs simultaneously with the W E low transition or after the W E transition, outputs remain in a high impedance state. 5. tCW is measured from the later of CE going low to the end of Write. 6. OE level is high or low. 7. Transition is measured ±500mV from steady. This parameter is sampled and not 100% tested.
