PRODUCT DESCRIPTION
The AD53032 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. 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 sig-
nal 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
signal lines
terminated to –2 V. Signal tracking capability is upwards of
5 V/ns.
The active load can be set for up to 35 mA load current with
less than a 10
μ
A linearity error through the entire set range.

and the buffered VCOM are independently adjustable.
Onboard Schottky diodes provide high speed switching and low
capacitance.
Also included on the chip is an onboard temperature sensor
whose purpose is to give an indication of the surface tempera-
ture of the DCL. This information can be used to measure
θ

and

or flag an alarm if proper cooling is lost. Output from
the sensor is a current sink that is proportional to absolute tem-
perature. The gain is trimmed to a nominal value of 1.0
μ
A/K.
As an example, the output current can be sensed by using a
10 k
resistor connected from +10 V to the THERM (IOUT) pin.
A voltage drop across the resistor will be developed that equals:

A/K = 10 mV/K = 2.98 V at room temperature.
