NOTES:
1. Connecting any terminal to voltages greater than V+ or less than GND may cause destructive latch-up. It is recommended that no inputs from
sources operating from external supplies be applied prior to “power up” of the TC7662B.
2. Derate linearly above 50
°C by 5.5 mW/°C.
3. In the test circuit, there is no external capacitor applied to pin 7. However, when the device is plugged into a test socket, there is usually a very
small but finite stray capacitance present, of the order of 5pF.
4. The TC7662B can operate without an external diode over the full temperature and voltage range. This device will function in existing designs which
incorporate an external diode with no degradation in overall circuit performance.

* 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 operation sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
