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

VEE. The upper-end of the common-mode voltage range is typically VCC - 2V, but either or both inputs can go to a maximum

of VCC + 0.2V without damage.

Note 2: Tested for +4.75V < VCC < +5.25V, and -5.25V < VEE < -4.75V with VDD = +5V, although permissible analog power-supply

range is +4.75V < VCC < +10.5V for single-supply operation with VEE grounded.

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.

Note 7: ICC tested for +4.75V < VCC < +10.5V with VEE grounded. IEE tested for -5.25V < VEE < -4.75V with VCC = +5V. IDD tested

for +4.75V < VDD < +5.25V with the worst-case condition of all four comparator outputs at logic low.
