*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 sections of the specifications is not implied.
Exposure to Absolute Maximum Rating Conditions for extended periods
may affect device reliability.
NOTES:
1. Input voltages may exceed supply voltages if input current is
limited to
±
100
μ
A.
2. Connecting any digital inputs or outputs to voltages greater
than V
+
or less than GND may cause destructive device latch-
up. Therefore, it is recommended that inputs from sources
other than the same power supply should not be applied to
the TC7109A before its power supply is established. In
multiple supply systems, the supply to the device should be
activated first.
3. This limit refers to that of the package and will not occur during
normal operation.
