    Note 2: All currents into device pins are positive; all currents out ot device
    pins are negative. All voltages are referenced to device ground unless
    otherwise specified.
    Note 3: All typicals are given for VCC = 5V and TA = 25°C.
    The q denotes specifications which apply over the full operating
    temperature range.
    Note 1: Absolute maximum ratings are those beyond which the safety of
    the device cannot be guaranteed.
