JA (junction to ambient) is for devices mounted to 5 in
2 FR4 PC board with one ounce copper where noted. When resistance
range is given, lower values are for 5 in2. Test PWB was 0.062 in thick and typically used 0.635-mm trace widths for power packages
and 1.3-mm trace widths for non-power packages with 100 x 100-mil probe land area at the end of each trace.

These parameters, although specified, are not 100% tested in production.
(3)
Temperature stability, sometimes referred to as average temperature coefficient, is described by the equation:
the appropriate temperature range. Note that the extremes in voltage do not necessarily occur at the extremes in temperature.
(4)
Output frequency equals oscillator frequency for the UC1842 and UC1843.
Output frequency is one half oscillator frequency for the UC1844 and UC1845.
