OPA1641 OPA1642 OPA1644 output stage

hello, reading the OPA1641 datasheet I don't understand the output stage. Can somebody help me simulating it using LTspice ? See attached .jpg

Hi,
the output is a push pull common emitter stage.
If there is a push pull common collector output stage in the voltage amp hidden in the opamp triangle then effectively this becomes a CFP output stage.
