The driver is a proprietary design that features three active states: Data High Mode, Data Low Mode and Term Mode as well as an Inhibit State. This facilitates the implementation of high speed active termination. The output voltage range is –3 V to +8 V to accommodate a wide variety of test devices. The output leakage is typically less than 250 nA over the entire signal range. The dual comparator, with an input range equal to the driver output range, features built-in latches and ECL-compatible outputs. The outputs are capable of driving 50 Ω signal lines terminated to –2 V. Signal tracking capability is upwards of 5 V/ns. Also included on the chip is an onboard temperature sensor whose purpose is to give an indication of the surface temperature of the D-C. This information can be used to measure θJC and θJA or flag an alarm if proper cooling is lost. Output from the COMPARATOR NC QL QLB LEL LELB LCOMP THERM 1.0mA/K 9, 33, 44, 46, 48 2, 5, 8 PWRGND ECLGND HQGND2 NC = NO CONNECT sensor is a current sink that is proportional to absolute temperature. The gain is trimmed to a nominal value of 1.0 µA/K. As an example, the output current can be sensed by using a 10 kΩ resistor connected from +10 V to the THERM (IOUT) pin. A voltage drop across the resistor will be developed that equals: 10K × 1 µA/K = 10 mV/K = 2.98 V at room temperature.

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Absolute maximum limits apply individually, not in combination. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2 Output short circuit protection to ground is guaranteed as long as proper heat sinking is employed to ensure compliance with the operating temperature limits. 3 To ensure lead coplanarity (± 0.002 inches) and solderability, handling with bare hands should be avoided and the device should be stored in environments at 24 °C ± 5°C (75°F ± 10°F) with relative humidity not to exceed 65%.

Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD53033 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. REV. 0 –5– WARNING!
