Note 1:
The input common-mode voltage and input signal voltages should not be allowed to go negative by more than 0.2V below
V
EE
. The upper-end of the common-mode voltage range is typically V
CC
- 2V, but either or both inputs can go to a maximum
of V
CC
+ 0.2V without damage.
Note 2:
Tested for +4.75V < V
CC
< +5.25V, and -5.25V < V
EE
< -4.75V with V
DD
= +5V, although permissible analog power-supply
range is +4.75V < V
CC
< +10.5V for single-supply operation with V
EE
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:
