NOTES: 1. Maximum package power dissipation limits must be observed to prevent thermal shutdown activation.
2. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
3. Tlow = 0°C for MC34166
= – 40°C for MC33166
Thigh = + 70°C for MC34166
= + 85°C for MC33166
