Single/Dual/Quad, Ultra-High-Speed, +3V/+5V, Beyond-the-Rails Comparators
General DescriptionThe MAX961–MAX964/MAX997/MAX999 are low-power,
ultra-high-speed comparators with internal hysteresis. These
devices are optimized for single +3V or +5V operation. The
input common-mode range extends 100mV Beyond-the-
Rails™, and the outputs can sink or source 4mA to within
0.52V of GND and VCC. Propagation delay is 4.5ns (5mV
overdrive), while supply current is 5mA per comparator.
The MAX961/MAX963/MAX964 and MAX997 have a shutdown mode in which they consume only 270μA sup-
ply current per comparator. The MAX961/MAX963 pro-
vide complementary outputs and a latch-enable feature.
Latch enable allows the user to hold a valid comparator
output. The MAX999 is available in a tiny 5-pin SOT23
package. The single MAX961/MAX997 and dual MAX962 are available in space-saving 8-pin μMAX® packages.

Absolute Maximum RatingsStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.

Note 1: The MAX961EUA/MAX962EUA/MAX997EUA/MAX999EUK are 100% production tested at TA = +25°C; all temperature
specifications are guaranteed by design.
Note 2: Inferred by CMRR. Either input can be driven to the absolute maximum limit without false output inversion, provided that the
other input is within the input voltage range.
Note 3: The input-referred trip points are the extremities of the differential input voltage required to make the comparator output
change state. The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis
zone. (See Figure 1.)
Note 4: Input offset voltage is defined as the mean of the trip points.
Note 5: CMRR = (VOSL - VOSH) / 5.2V, where VOSL is the offset at VCM = -0.1V and VOSH is the offset at VCM = 5.1V.
Note 6: PSRR = (VOS2.7 - VOS5.5) / 2.8V, where VOS2.7 is the offset voltage at VCC = 2.7V, and VOS5.5 is the offset voltage at
VCC = 5.5V.
Note 7: Propagation delay for these high-speed comparators is guaranteed by design characterization because it cannot be accurately
measured using automatic test equipment. A statistically significant sample of devices is characterized with a 200mV step and
100mV overdrive over the full temperature range. Propagation delay can be guaranteed by this characterization, since DC
tests ensure that all internal bias conditions are correct. For low overdrive conditions, VTRIP is added to the overdrive.
Note 8: Guaranteed by design.
