TC7652 ELECTRICAL SPECIFICATIONS

*Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device.

These are stress ratings only and functional operation of the

device at these or any other conditions above those indi-

cated in the operation sections of the specifications is not

implied. Exposure to Absolute Maximum Rating conditions

for extended periods my affect device reliability.

Electrical Characteristics: VDD = +5V, VSS = -5V, TA = +25°C, unless otherwise indicated.

Limiting input current to 100µA is recommended to avoid latch-up problems. Typically 1mA is safe however, this is not

guaranteed.

Output clamp not connected. See typical characteristics curves for output swing versus clamp current characteristics.

See “Output Clamp” under detailed description.
