DEVICE OPERATION
The modes of operation of the M87C257 are listed
in the Operating Modes. A single power supply is
required in the read mode. All inputs are TTL levels
except for V
PP
and 12V on A9 for Electronic Signa-
ture.
Read Mode
The M87C257 has two control functions, both of
which must be logically active 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

Notes:
1. 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.
2. Minimum DC voltage on Input or Output is –0.5V with possible undershoot to –2.0V for a period less than 20ns. Maximum DC
voltage on Output is V
CC
+0.5V with possible overshoot to V
CC
+2V for a period less than 20ns.
