... CC EE are ideal for level translators and bipolar to single- ended converters. The single MAX985 is available in a chip-scale pack- age (UCSP™), significantly reducing the required PC board area. The single MAX985/MAX986 are available in 5-pin SC70 packages and the dual MAX989/MAX990 are available in 8-pin SOT23 packages. ...

... Unfortunately, this method also slows hysteresis response time. Use the following procedure to calcu- late resistor values for the MAX985/MAX989/MAX993. 1) Select R3. Leakage current under 10nA, so the current through R3 should be at least 1µA to minimize errors caused by leakage current. The cur- rent through R3 at the trip point ...

... V THR THF MAX986/MAX990/MAX994 The MAX986/MAX990/MAX994 have ±3mV internal hysteresis. They have open-drain outputs and require an external pullup resistor (Figure 2). Additional hys- teresis can be generated using positive feedback, but the formulas differ slightly from those of the MAX985/MAX989/MAX993 ...

... Micropower, Low-Voltage, UCSP/SC70, Zero-Crossing Detector Figure 3 shows a zero-crossing detector application. The MAX985’s inverting input is connected to ground, and its noninverting input is connected to a 100mV signal source. As the signal at the noninverting input crosses 0V, the comparator’s output changes state. Logic-Level Translator Figure 4 shows an application that converts 5V logic lev- els to 3V logic levels. The MAX986 is powered by the 5V supply voltage, and the pullup resistor for the MAX986’ ...
