TC7660S

Notice†: Stresses above those listed under “Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of

the device at those or any other conditions above those

indicated in the operational sections of this

specification is not intended. Exposure to maximum

rating conditions for extended periods may affect

device reliability.

Note 1: Connecting any input 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 TC7660S.

2: Derate linearly above +50°C by

5.5 mW/°C.

ELECTRICAL SPECIFICATIONS

Electrical Characteristics: Unless otherwise noted, specifications measured over operating temperature range with

V+ = 5V, COSC = 0, refer to test circuit in Figure 4-1.
