MRF89XA

5.1

ESD Notice

The MRF49XA is a high-performance radio frequency

device, it satisfies:

? Class II of the JEDEC standard JESD22-A114-B

(Human Body Model) of 2 KV, except on all of the

RF pins where it satisfies Class 1A.

? Class III of the JEDEC standard JESD22-C101C

(Charged Device Model) on all pins.

It should thus be handled with all the necessary ESD

precautions to avoid any permanent damage.
