Note:
Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings" may cause
permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those
indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods
may affect device reliability. Refer also to the SGS-THOMSON SURE Program and other relevant quality documents.
Table 2. Absolute Maximum Ratings
DEVICE OPERATION
The seven modes of operations of the M2764A are
listed in the Operating Modes table. A single 5V
power supply is required in the read mode. All
inputs are TTL levels except for V
PP
and 12V on A9
for Electronic Signature.
Read Mode
The M2764A has two control functions, both of
which must be logically satisfied in order to obtain
data at the outputs. Chip Enable (E) is the power
control and should be used for device selection.
Output Enable (G) is the output control and should
be used to gate data to the output pins, inde-
pendent of device selection.
Assuming that the addresses are stable, address
access time (t
AVQV
) is equal to the delay from E to
output (t
ELQV
). Data is available at the outputs after
the falling edge of G, assuming that E has been low
and the addresses have been stable for at least
t
AVQV
-t
GLQV
.
Standby Mode
The M2764A has a standby mode which reduces
the maximum active power current from 75mA to
35mA. The M2764A is placed in the standby mode
by applying a TTL high signal to the E input. When
in the standby mode, the outputs are in a high
impedance state, independent of the G input.
Two Line Output Control
Because EPROMs are usually used in larger mem-
ory arrays, the product features a 2 line control
function which accommodates the use of multiple
memory connection. The two line control function
allows :
a. the lowest possible memory power dissipation,
b. complete assurance that output bus contention
will not occur.
