SRAM CMOS 64K, 623308, DIP28 - 

The A623308A-70SF is a 8K x 8-bit CMOS SRAM IC with low operating current 65536-bit static random access memory organized as 8192 words by 8-bit and operates on a voltage from 4.5 to 5.5V. Inputs and 3-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 2V.
