Meaning

Power supply voltage

Input voltage

Output voltage

Output current

Operating temperature

Storage temperature

VDD33, VDD25 Indicates voltage range within which damage or reduced reliability will not result when

power is applied to a VDD pin.

VI

Indicates voltage range within which damage or reduced reliability will not result when

power is applied to an input pin.

VO

Indicates voltage range within which damage or reduced reliability will not result when

power is applied to an output pin.

IO

Indicates absolute tolerance value for DC current to prevent damage or reduced

reliability when a current flows out of or into an output pin.

TA

Indicates the ambient temperature range for normal logic operations.

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

Symbol

Meaning

Power supply voltage

High-level input voltage

Low-level input voltage

Hysteresys voltage

Input rise time

Input fall time

VDD33, VDD25 Indicates the voltage range for normal logic operations occur when VSS = 0 V.

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.

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.

VH

Indicates the differential between the positive trigger voltage and the negative trigger

voltage.

tri

Indicates allowable input rise time to input pins. Input rise time is transition time from

0.1 × VDD to 0.9 × VDD.

tfi

Indicates allowable input fall time to input pins. Input fall time is transition time from 0.9

× VDD to 0.1 × VDD.
