A9 &

All other pins (Note 1) ……………… -0.5V to VCC + 0.5V

Output Short Circuit Current (Note 3) ……………..200mA

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

+1.5V for periods up to 20ns.

2. Minimum DC input voltage on A9 pins is -0.5V. During

voltage

transitions,

A9,

RESET

may

overshoot VSS to -2.0V for periods of up to 20ns.

Maximum DC input voltage on A9 and

which may overshoot to 12.5V 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

Commercial Devices

°C to +70°C

Extended Range Devices

°C to +85°C

VCC Supply Voltages

VCC for 0

°C ~ +70°C …………………….. +2.7V to +3.6V

VCC for -40

°C ~ +85°C (-U series) ………+3.0V to +3.6V

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.
