    I'm looking for the output capacitance of a 7406 Vcc=30V device.
    I don't see it on any data sheets.

    Off or on ?:)

    Just measure it, or imply it from the rise-time using a high-valued
    pull-up resistor.

    My guru that ask about it said "I'll bet it was on the data sheet when
    it first came out, but I don't see it now. I could measure it but I don't
    want to."
    Oh well,

    No it was never on any datasheet and I have some pretty old ones and the
    designing with TTL text by the TI staff.

    You can infer it from the propagation delay test circuits as test load
    capacitance divided by max fanout spec'd for the part. It is not much.
