General Description
Minimum standby power is drawn by this device when
The A625308A is a low operating current 262,144-bit
static random access memory organized as 32,768
words by 8 bits and operates on a voltage from 4.5V to
5.5V.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.
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.
