GENERAL DESCRIPTION
The ADATE205 is a complete, single-chip solution that
performs the pin electronics functions of driver, comparator,
and active load (DCL) for ATE applications. The active load can
be powered down if not used.
The driver is a proprietary design that features three active
modes: data high mode, data low mode, and term mode, as well
as an inhibit state.
The driver has low leakage (<10 nA) in High-Z mode. The
output voltage range is −1.5 V to +6.5 V to accommodate a wide
variety of test devices.
The ADATE205 supports four programmable Tr/Tf times for
applications where slower edge rates are required. The edge rate
selection is done via two static digital CMOS select bits. The
input data to the driver can be inverted using a single CMOS
logic bit. This feature can be used for system calibration or
applications where complement input data is needed.

tPD measured from the 50% of enable signal to 50% of output.

The low leakage mode of the comparator, controlled by VLLM input, reduces the leakage due to the comparator input. The comparator operates in this mode, but its
bandwidth is compromised and is not guaranteed.
5
Under no circumstances should the input voltages exceed the supply voltages.

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.
ESD 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 this product 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.

THEORY OF OPERATION
The ADATE205 has two general classes of logic inputs:
differential inputs for controlling functions that generally need
to be operated at high speed, and single-ended CMOS inputs
for setting operating modes or other low speed functions. The
differential inputs have a wide common-mode range that allows
them to be used with a variety of logic families. The differential
inputs can also be used single-ended, with one input from each
pair of inputs tied to a fixed reference, but this makes precise
timing more difficult to achieve.
These differential input pins provide 50 Ω input termination
resistors for use as desired. The single-ended inputs have an
input range compatible with most logic families and are high
impedance to make driving them very easy. The switching
threshold for the single-ended inputs is preset to one-half of the
voltage at the CMOS_VDD pin.
