Extended Range Devices
1. Minimum DC voltage on input or I/O pins is -0.5V. During
voltage transitions, input or I/O pins may undershoot VSS
to -2.0V for periods of up to 20ns. Maximum DC voltage
on input and I/O pins is VCC +0.2V. During voltage
transitions, input or I/O pins may overshoot to VCC +2.0V
for periods up to 20ns.

Operating ranges define those limits between which the
functionally of the device is guaranteed.
During voltage transitions, A9 and
may overshoot
OE
VSS to -2.0V for periods of up to 20ns. Maximum DC
input voltage on A9 is +12.5V which may overshoot to
14.0V 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.
