Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Maximum package power dissipation limits must be observed.
2. ESD protection per JEDEC JESD22−A114−F for HBM, per JEDEC JESD22−A115−A for MM, and per JEDEC JESD22−C101D for CDM.
This device contains latchup protection and exceeds 100 mA per JEDEC Standard JESD78.
ELECTRICAL CHARACTERISTICS (V_CC = 12 V (Note 3), for typical values T_A = 25°C, for min/max values T_A is the operating
ambient temperature range that applies (Note 4), unless otherwise noted.)

3. Adjust V_CC above the startup threshold before setting to 12 V.
4. T_low = 0°C for MC34262
T_high = +85°C for MC34262
= −40°C for MC33262
= +105°C for MC33262.
