2.2 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
VI
Indicates voltage range within which damage or reduced reliability will not
result when power is applied to an input pin.
Output voltage
VO
Indicates voltage range within which damage or reduced reliability will not
result when power is applied to an output pin.
Operating temperature
TA
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
Off-state output leakage current
IOZ
Output short circuit current
IOS
Input leakage current
II
Low-level output current
IOL
High-level output current
IOH
Meaning
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.
Indicates the current that flows when the output pin is shorted (to GND pins)
when output is at high-level.
Indicates the current that flows when the input voltage is supplied to the
input pin.
Indicates the current that flows to the output pins when the rated low-level
output voltage is being applied.
Indicates the current that flows from the output pins when the rated high-
level output voltage is being applied.
