Notes
1. ESD testing is performed in accordance with the Human Body Model (HBM) (C_ZAP = 100 pF, R_ZAP = 1500 Ω), the Machine Model (MM)
(C_ZAP = 200 pF, R_ZAP = 0 Ω), and the Charge Device Model (CDM), Robotic (C_ZAP = 4.0pF).
2. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
3. With 2.0 in² of copper heatsink.
4. ESD1 testing is performed in accordance with the Human Body Model (C_ZAP = 100pF, R_ZAP = 1500Ω).
5. With no additional heatsinking.
6. Maximum quiescent power dissipation is 0.25W.
7. 13V ≤ V_B+ ≤ 32V and -20°C ≤ T_J ≤ 145°C, unless otherwise noted.
