PRODUCT DESCRIPTION

The AD53033 is a single chip that performs the pin electronics
functions of driver and comparator (D-C) in ATE VLSI and
memory testers.

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 tempera-

ture of the D-C. This information can be used to measure θ
and θ

or flag an alarm if proper cooling is lost. Output from the

sensor is a current sink that is proportional to absolute tempera-

ture. 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.

NOTES

1

Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. 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%.

CAUTION

ESD (electrostatic discharge) sensitive device. 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.
