ELECTRICAL CHARACTERISTICS:
Unless otherwise stated, these specifications apply for -55°C
≤ TA ≤ 125°C for the
UC184X; -40°C
≤ TA ≤ 85°C for the UC284X; 0°C ≤ TA ≤ 70°C for the 384X; VCC = 15V
(Note 5); RT = 10k; CT = 3.3nF, TA=TJ.
Note 2:
These parameters, although guaranteed, are not 100% tested in production.
Note 3:
Parameter measured at trip point of latch with VPIN 2 =0.
Note 4:

Note 5:
Adjust VCC above the start threshold before setting at 15V.
Note 6:
Output frequency equals oscillator frequency for the UC1842 and UC1843.
Output frequency is one half oscillator frequency for the UC1844 and UC1845.
Note 7:
Temperature stability, sometimes referred to as average temperature coefficient, is described by the equation:

VREF (max) and VREF (min) are the maximum and minimum reference voltages measured over the appropriate
temperature range. Note that the extremes in voltage do not necessarily occur at the extremes in temperature.
