Absolute Maximum Ratings*  
*Comments  
Stresses above those listed under "Absolute Maximum  
Ratings" may cause permanent damage to this device.  
These are stress ratings only. Functional operation of  
this device at these or any other conditions above  
those indicated in the operational sections of these  
specification is not implied or intended. Exposure to  
the absolute maximum rating conditions for extended periods  
may affect device reliability.

Notes:  
Operating Ranges  
1. Minimum DC voltage on input or I/O pins is -0.5V. During  
voltage transitions, inputs may undershoot VSS to -2.0V  
for periods of up to 20ns. Maximum DC voltage on output  
and I/O pins is VCC +0.5V. During voltage transitions,  
outputs may overshoot to VCC +2.0V for periods up to  
20ns.

2. Minimum DC input voltage on A9 pins is -0.5V. During  
VCC Supply Voltages  
voltage transitions, A9 and  
may overshoot VSS to -  
OE  
2.0V for periods of up to 20ns. Maximum DC input  
voltage on A9 and is +12.5V which may overshoot to  
VCC for ± 10% devices ….. ….. . . . . . . . . . . +4.5V to +5.5V  
Operating ranges define those limits between which the  
functionally of the device is guaranteed.  
OE  
13.5V for periods up to 20ns.  
3. No more than one output is shorted at a time. Duration of  
the short circuit should not be greater than one second.  
Device Bus Operations  
This section describes the requirements and use of the  
device bus operations, which are initiated through the  
internal command register. The command register itself does  
not occupy any addressable memory location. The register is  
composed of latches that store the commands, along with  
the address and data information needed to execute the  
command. The contents of the register serve as inputs to the  
internal state machine. The state machine outputs dictate the  
function of the device. The appropriate device bus  
operations table lists the inputs and control levels required,  
and the resulting output. The following subsections describe  
each of these operations in further detail.
