DESCRIPTION OF OPERATION

General operation (CMOS Output)

In reference to following the block diagram of CMOS output VDA series ;

provided at the output terminal because N-ch transistor is OFF and the P-ch transistor is ON. And,

the output maintains the same level of input as long as the input voltage remains above the detection

ON and the P-ch transistor is OFF. And, the

minimum operating voltage, the output becomes
