Package and store only in conductive foam, antistatic tubes, or other conducting material. Use proper antistatic handling pro- cedures. Do not connect in circuits under “power-on” conditions, as high transients may cause permanent damage. TC7109/TC7109A ELECTRICAL SPECIFICATIONS (Continued) Electrical Characteristics: All parameters with V+ = +5V, V- = -5V, GND = 0V, TA = +25°C, unless otherwise indicated. Symbol Parameter Min Typ Max Unit Test Conditions Note 1: Input voltages may exceed supply voltages if input current is limited to ±100 μA. 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. |
