SERIAL INTERFACE ADAPTER FOR
TC500 A/D CONVERTER FAMILY
TC520A
* Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the Operational Specifications is not implied. Any exposure to
Absolute Maximum Rating Conditions may affect device reliability.
