Note 1: Trip Point is defined as the input voltage required to make the comparator output change state. The difference

between upper (VTRIP+) and lower (VTRIP-) trip points is equal to the width of the input-referred hysteresis zone (VHYST).

Specified for an input common-mode voltage (VCM) of 0V (see Figure 1).

Note 2: Input Offset Voltage is defined as the center of the input-referred hysteresis zone. Specified for VCM = 0V (see Figure 1).

Note 3: 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 VCMR 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.

Note 4: 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).

Note 5: Tested over the full input voltage range (VCMR).

Note 6: 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.

Note 7: Positive Supply Current specified with the worst-case condition of all outputs at logic low (MAX907/MAX908), and

with V+ = 5.5V.

Note 8: Typical power specified with V+ = 5V; maximum with V+ = 5.5V (and with V- = -5.5V for MAX909).

Note 9: Due to difficulties in measuring propagation delay with 5mV of overdrive in automatic test equipment, this parameter is

guaranteed by design for the MAX907 and MAX908. Correlation tests show that the specification can be guaranteed if all

other DC parameters are within the specified limits. VOS must be added to the overdrive voltage for low values of overdrive.

For the MAX909, propagation delay is typical only and there is no guaranteed maximum limit.

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 (tPD+)

and high-to-low transition (tPD-), and also between the QOUT and QOUT transition on the MAX909.

Note 12: Latch specifications apply to MAX909 only (see Figure 2).
