Hi Team,

Is the output type of SN74HC42 push-pull or open-drain?

Beat Regards,

    This device has push/pull outputs. Open-drain outputs would not have a VOH specification.

    Furthermore, open-drain outputs would be shown in the functional block diagram, and mentioned everywhere in the description; compare the SN74HCS165 and SN74HCS16507 datasheets.
