ELECTRICAL CHARACTERISTICS (VCC = 12 V [Note 2], ROSC= 18.2 k, RVFO = 2940, COSC = 300 pF, RT = 2370 k, CT = 300 pF,
CL = 1.0 nF. For typical values TA = 25°C, for min/max values TA is the operating ambient temperature range that applies [Note 3], unless
otherwise noted.)

NOTES: 1. Maximum package power dissipation limits must be observed.
2. Adjust VCC above the Startup threshold before setting to 12 V.
3. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
