Notes:

1. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

2. The absolute value of VDD5 and VSS5 must always be less than or equal to the absolute value of VDD15 and

VSS15.

3. The TLD4012 incorporates an exposed die pad on the underside of its package. This acts as a heat sink

and must be connected to a copper plane on the printed circuit board for proper heat dissipation.

Failure to do so may result in exceeding the maximum junction temperature which could permanently

damage the device. This copper plane must be connected to VSS15. See the Application Information

section of this document for additional information.

4. Application must insure that VSS15 is applied before VSS5. A clamp diode connected between VSS5 and

VSS15 can be used to insure proper application of supply voltages to the TLD4012 (see Test/Application

Circuits of this document). Note that only one diode is needed per board for multi-channel line cards, but diode

selection should account for the increased current transient that the diode must carry for multiple channels. If

the +/-5V rail’s rise time is fast, for example in applications in which the driver’s supplies might be hot-plugged,

this method may not be sufficient and supply sequencing may be necessary.
