Single/Dual/Quad High-Speed, Ultra Low-Power,

Single-Supply TTL Comparators

Note 1:

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

Note 2:

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

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:

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, the

MAX907/MAX908/MAX909 are sample tested to 0.1% AQL with 100mV input overdrive. Correlation tests show that the

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 12: Latch specifications apply to MAX909 only. See Figure 2.
