Notes:

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 +0.5V. During voltage

transitions, input or I/O pins may overshoot to VCC +2.0V

for periods up to 20ns.

2. Minimum DC input voltage on A9,

OE and RESET is

-

0.5V. During voltage transitions, A9,

OE and RESET

may overshoot 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.

*Comments

Stresses above those listed under "Absolute Maximum

of

these

specification is not implied or intended. Exposure to

the absolute maximum rating conditions for extended periods

may affect device reliability.

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.
