ESD/Latch-Up-Protection

All pins have an ESD protection of >± 2000V according the Human Body Model (HBM) except for pin 8, which

has a protection level of >± 1000V. The ESD test follows the Human Body Model with 1.5 kΩ/100 pF based on

MIL 883-G, Method 3015.7.

Latch-up protection of >± 100mA has been proven based on JEDEC No. 78A Feb. 2006, temperature class 1.
