Note 1:
Trip Point is defined as the input voltage required to make the comparator output change state. The difference
between upper (V
TRIP
+) and lower (V
TRIP
-) trip points is equal to the width of the input-referred hysteresis zone (V
HYST
).
Specified for an input common-mode voltage (V
CM
) of 0V. See Figure 1.
Input Offset Voltage is defined as the center of the input-referred hysteresis zone. Specified for V
CM
= 0V. See Figure 1.
Inferred from the CMRR test. Note that a correct logic result is obtained at the output, provided that at least one input is
within the V
CMR
limits. Note also that either or both inputs can be driven to the upper or lower absolute maximum limit with-
out damage to the part.
Tested with V+ = 5.5V (and V- = 0V for MAX909). MAX909 also tested over the full analog input range (i.e., with
V- = -5.5V).
Tested over the full input voltage range (V
CMR
).
Specified over the full tolerance of operating supply voltage: MAX907/MAX908 tested with 4.5V < V+ < 5.5V. MAX909
tested with 4.5V < V+ < 5.5V and with -5.5V < V- < 0V.
Positive Supply Current specified with the worst-case condition of all outputs at logic low (MAX907/MAX908), and
with V+ = 5.5V.
Typical power specified with V+ = 5V; maximum with V+ = 5.5V (and with V- = -5.5V for MAX909).
Due to difficulties in measuring propagation delay with 5mV of overdrive in automatic test equipment, the
MAX907/MAX908/MAX909 are sample tested to 0.1% AQL with 100mV input overdrive. Correlation tests show that the
specification can be guaranteed if all other DC parameters are within the specified limits. V
OS
must be added to the over-
drive voltage for low values of overdrive.
Note 10:
Differential Propagation Delay is specified as the difference between any two channels in the MAX907/MAX908 (both out-
puts making either a low-to-high or a high-to-low transition).
Note 11:
Propagation Delay Skew is specified as the difference between any single channel’s output low-to-high transition (t
PD
+)
and high-to-low transition (t
PD
-), and also between the QOUT and
Q
OUT transition on the MAX909.
Note 12:
Latch specifications apply to MAX909 only. See Figure 2.
