General Description
The A23W8308 high-performance Read Only Memory is
configured as 262,144 x 8 bits. It is designed to be
compatible with all microprocessors and similar
applications where high-performance, large-bit storage,
and
simple
interfacing
are
important
design
considerations. This device is designed for use with
operating voltage from 3V to 5V.
The A23W8308 offers an automatic POWER-DOWN
controlled by the Chip Enable CE/ CE input. When
CE/ CE goes low/high, the device will automatically
POWER-DOWN and remain in a low power STANDBY
mode as long as CE/ CE remains low/high. A23W8308
also offers OE/ OE /NC (Active High or Low or No
Connection), which eliminates bus contention in multiple
bus microprocessor systems.

2. VIN = VIH/VIL, but OE/CE = VIH, OE / CE = VIL (Output is unloaded)
3. This parameter is periodically sampled and is not 100% tested. All pins, except pins under test, are tied to AC ground.
4. Output LOW impedance delay (tLZ) is measured from CE or OE going active.
