... PCMCIA Cards Upgrade for LT1016 Designs GENERAL DESCRIPTION The AD8561 is a single 7 ns comparator with separate input and output sections. Separate supplies enable the input stage to be operated from 5 V dual supplies and +5 V single supplies. Fast 7 ns propagation delay makes the AD8561 a good choice for timing circuits and line receivers ...

... 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 the AD8561 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 +3.0 V, V– ...

... LT1016—input voltage range, input bias currents, speed, out- put swing and power consumption. When operated single supply, the LT1016 has an input voltage range from +1. +3.5 V. The AD8561 has a wider input range from 3.0 V. Signals above 3.0 V may result in slower response times (see Figure 8). If both signals exceed 3 ...
