Understand the difference.
Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.
XNOR
SymbolsExclusive-NOR gate
For two positive-logic inputs, produces a true output when the input states are equal.

A distinction that matters
XNOR specifies a logical function; an open-drain implementation is a separate electrical output characteristic.
XOR
SymbolsExclusive-OR gate
For two positive-logic inputs, produces a true output when the input states differ.

A distinction that matters
Two-input XOR is not inclusive OR; for more inputs verify whether the device implements odd parity or another specified function.
