Notes:

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

voltage transitions, A9 and

OE may overshoot VSS to -

2.0V for periods of up to 20ns. Maximum DC input

voltage on A9 and

OE is +12.5V which may overshoot to

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.

*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.

Operating Ranges

VCC for ± 10% devices ….. ….. . . . . . . . . . . +4.5V to +5.5V

Operating ranges define those limits between which the

functionally of the device is guaranteed.

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.
