Glossary - alphabet order - "I"

I²C-BUS interface

This is a type of serial interface, originally proposed by Royal NXP semiconductors.


Initial tolerance

This refers to initial deviation (Δf) between the actual frequency (measured value) and the rated value (f) at an ambient temperature of +25 ℃. This differential is expressed as a ratio (Δf/f).

Reference: Frequency tolerance


Insulation resistance

This is the resistance value between the leads and between the leads and the case.


Inverter

An inverter is a circuit element that outputs a signal whose high/low status is the reverse of the corresponding input signal. Inverters are used in crystal oscillation circuit to help generate crystal oscillation.
