AT27C256R  
Absolute Maximum Ratings*  
*NOTICE:  
Stresses beyond those listed under “Absolute Maxi-  
mum Ratings” may cause permanent damage to  
the device. This is a stress rating only and func-  
tional operation of the device at these or any other  
conditions beyond those indicated in the opera-  
tional sections of this specification is not implied.  
Exposure to absolute maximum rating conditions  
for extended periods may affect device reliability.  
Temperature Under Bias................................ -55°C to +125°C  
Storage Temperature..................................... -65°C to +150°C  
Voltage on Any Pin with  
Respect to Ground .........................................-2.0V to +7.0V(1)  
Voltage on A9 with  
Respect to Ground ......................................-2.0V to +14.0V(1)  
VPP Supply Voltage with  
Respect to Ground .......................................-2.0V to +14.0V(1)  
Note:  
1. Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns.Maximum output pin voltage is  
VCC + 0.75V dc which may overshoot to +7.0 volts for pulses of less than 20 ns.

3. VH = 12.0 ± 0.5V.  
4. Two identifier bytes may be selected. All Ai inputs are held low (VIL), except A9 which is set to VH and A0 which is toggled low  
(VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte.
