GENERAL DESCRIPTION
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. I
the buffered VCOM are independently adjustable. On-board
Schottky diodes provide high speed switching and low
capacitance.
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 θ
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
Rev. B
