The AD53509 is a single chip that performs the pin electronics
functions of driver, comparator, and active load in ATE VLSI
and memory testers. In addition, a Schottky diode bridge for
the active load and a VCOM buffer are included internally.
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. The output voltage range is −2 V to +7 V to
accommodate a wide variety of test devices. The output leakage
is typically <250 nA over the 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 >5 V/ns.
The active load can be set up to 40 mA load current with less
than a 10 μA linearity error through the set range. IOH, IOL, and
the buffered VCOM are independently adjustable. On-board
Schottky diodes provide high speed switching and low
capacitance.

GENERAL DESCRIPTION
Figure 1.
Also included on the chip is an on-board temperature sensor
whose purpose is to give an indication of the surface temperature
of the DCL. This information can be used to measure θJC and θJA
or flag an alarm if proper cooling is lost. Output from the sensor
is a current sink that is proportional to absolute temperature.
The gain is trimmed to a nominal value of 1.0 μA/K. For example,
the output current can be sensed by using a 10 kΩ resistor
connected from 10 V to the THERM pin. A voltage drop across
the resistor then develops that equals
10 K × 1 μA/K = 10 mV/K = 2.98 V (at room temperature)

ABSOLUTE MAXIMUM RATINGS
Stresses above those listed under Absolute Maximum Ratings
may cause permanent 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
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Output short-circuit protection is guaranteed as long as proper heat sinking
is employed to ensure compliance with the operating temperature limits.

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%.
