... Not Recommended for New Designs The MAX900 was manufactured for Maxim by an outside wafer foundry using a process that is no longer available not recommended for new designs. A Maxim replacement or an industry second-source may be available. The data sheet remains available for existing users. ...

... TTL-logic outputs with active internal pull- ups. Fast propagation delay (8ns typ at 5mV overdrive) makes the MAX900–MAX903 ideal for fast A/D convert- ers and sampling circuits, line receivers, V/F converters, and many other data-discrimination applications. ...

... Note 4: Guaranteed by design. Times are for 100mV step inputs (see Propagation Delay Characteristics in Figures 2 and 3). Note 5: Maximum difference in propagation delay between any of the four comparators in the MAX900–MAX903. Note 6: See Timing Diagram (Figure 2). Owing to the difficult and critical nature of switching measurements involving the latch, these parameters cannot be tested in a production environment ...

... Input Slew-Rate Requirements As with all high-speed comparators, the high gain-band- width product of the MAX900–MAX903 can create oscil- lation problems when the input traverses the linear region. For clean output switching without oscillation or steps in the output waveform, the input must meet mini- mum slew-rate requirements ...
