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.

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. 2 Rev. 0 | Page 7 of 16 ADATE205 ABSOLUTE MAXIMUM RATINGS Table 2. Parameter Maximum Current for VCC Maximum Current for VEE Positive Supply Voltage (VCC to GND) Negative Supply Voltage (VEE to GND) Operating Temperature (Junction) Storage Temperature Range ESD (Human Body Model) Rating 205 mA 270 mA +10.5 V −5.5 V +150°C −65°C to +150°C ±1500 V 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.

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. Table 4.
