... Power-Up Delay Note 1: The MAX998EUT specifications are 100% tested at T teed by design, not production tested. Note 2: Inferred from CMRR test. Either input can be driven to the absolute maximum limit without false output inversion, as long as the other input is within the common-mode voltage range. Note defined as the mean of trip points ...

... The MAX998 features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA. Activate shutdown mode by driving SHDN low. The MAX976/MAX978/MAX998 comparator inputs have a common-mode voltage range of -0. _______________________________________________________________________________________ MAX976 TOC16 > V ...

... This tends to occur when the voltage on one input is equal to or very close to the voltage on the other input. The MAX976/MAX978/MAX998 have inter- nal hysteresis to counter parasitic effects and noise. The hysteresis in a comparator creates two trip points: one for the rising input voltage and one for the falling input voltage (Figure 1) ...

... R1, R2, and R3. OUTA provides an active-low undervoltage indication, and OUTB gives an active-low overvoltage indication. MAX976 ANDing the two outputs provides an active-high, MAX978 power-good signal. The design procedure is as follows: MAX998 1) Select R1. The leakage current into INB- is normally 75nA, so the current through R1 should exceed 1.0µ ...
