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 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
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
JC
and
θ
JA 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 k
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.
