The chip enable function (CE function) and enable function (EN function) are functions that stop all IC operations or part of its functions.
When the IC and part of its functions are operating, it is called to be enabled.
Conversely, when the operation of the IC and part of its functions is stopped, it is called to be disabled.
Generally, in the disabled state where the IC and part of its functions are stopped, output stops and the quiescent current is reduced.
The detailed operation differs depending on the IC, so check the specifications of the IC to be used.
