Note 1: The input common-mode voltage and input signal voltages should not be allowed to go negative by more than 0.2V below

Note 3: Specification does not apply to MAX901.

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. Typical specifications listed are taken from measurements

using a high-speed test-jig.
