Terminology

Terms Used in Absolute Maximum Ratings

Parameter

Symbol

Meaning

Power supply voltage

VDD

Indicates voltage range within which damage or reduced reliability will not

result when power is applied to a VDD pin.

Input voltage

Indicates voltage range within which damage or reduced reliability will not

result when power is applied to an input pin.

Output voltage

Indicates voltage range within which damage or reduced reliability will not

result when power is applied to an output pin.

Operating temperature

Indicates the ambient temperature range for normal logic operations.

Storage temperature

Tstg

Indicates the element temperature range within which damage or reduced

reliability will not result while no voltage or current are applied to the device.

Terms Used in Recommended Operating Range

Parameter

Symbol

Meaning

Power supply voltage

VDD

Indicates the voltage range for normal logic operations occur when VSS = 0V.

High-level input voltage

VIH

Indicates the voltage, which is applied to the input pins of the device, is the

voltage indicates that the high level states for normal operation of the input

buffer.

* If a voltage that is equal to or greater than the “MIN.” value is applied, the

input voltage is guaranteed as high level voltage.

Low-level input voltage

VIL

Indicates the voltage, which is applied to the input pins of the device, is the

voltage indicates that the low level states for normal operation of the input

buffer.

* If a voltage that is equal to or lesser than the “MAX.” value is applied, the

input voltage is guaranteed as low level voltage.

Terms Used in DC Characteristics

Parameter

Symbol

Meaning

Off-state output leakage current

IOZ

Indicates the current that flows from the power supply pins when the rated

power supply voltage is applied when a 3-state output has high impedance.

Output short circuit current

IOS

Indicates the current that flows when the output pin is shorted (to GND pins)

when output is at high-level.

Input leakage current

Indicates the current that flows when the input voltage is supplied to the

input pin.

Low-level output current

IOL

Indicates the current that flows to the output pins when the rated low-level

output voltage is being applied.

High-level output current

IOH

Indicates the current that flows from the output pins when the rated high-

level output voltage is being applied.
