*NOTICE: Stresses beyond those listed under “Absolute Maxi-  
mum Ratings” may cause permanent damage to the device.  
This is a stress rating only and functional operation of the  
device at these or any other conditions beyond those indi-  
cated in the operational sections of this specification is not  
implied. Exposure to absolute maximum rating conditions  
for extended periods may affect device reliability.  
Note: 1. Minimum voltage is -0.6V dc which may undershoot  
to -2.0V for pulses of less than 20 ns. Maximum out-  
put pin voltage is VCC + 0.75V dc which may over-  
shoot to +7.0V for pulses of less than 20 ns.

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 Identi-  
fication byte and high (VIH) to select the Device Code byte.
