The device has eight bi-directional input-output lines to
provide simultaneous access to all bits in a word. An
automatic power down feature permits the on-chip circuitry
to enter a very low standby mode and be brought back into
operation at a speed equal to the address access time.
A Low Power version with 2V Data Retention (EDI88128LPS)
is also available for battery back-up opperation. Military
product is available compliant to MIL-PRF-38535.
* 15ns access time is advanced information, contact factory for availability.
This product is subject to change without notice.
