_________________General Description
____________________________Features
♦ Ultra-Fast, 4.5ns Propagation Delay
The 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
♦ Ideal for +3V and +5V Single-Supply Applications
♦ Beyond-the-Rails Input Voltage Range
♦ Low, 5mA Supply Current (MAX997/MAX999)
♦ 3.5mV Internal Hysteresis for Clean Switching
♦ Output Latch (MAX961/MAX963)
or source 4mA to within 0.52V of GND and V
.
CC
Propagation delay is 4.5ns (5mV overdrive), while sup-
ply current is 5mA per comparator.
The MAX961/MAX963/MAX964 and MAX997 have a
shutdown mode in which they consume only 270µA
supply current per comparator. The MAX961/MAX963
provide complementary outputs and a latch-enable fea-
ture. Latch enable allows the user to hold a valid com-
parator output. The MAX999 is available in a tiny
SOT23-5 package. The single MAX961/MAX997 and
dual MAX962 are available in space-saving 8-pin µMAX
packages.
♦ TTL/CMOS-Compatible Outputs
♦ 270µA Shutdown Current per Comparator
(MAX961/MAX963/MAX964/MAX997)
♦ Available in Space-Saving Packages:
5-Pin SOT23 (MAX999)
8-Pin µMAX (MAX961/MAX962/MAX997)
16-Pin QSOP (MAX964)

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 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, V
is added to the overdrive.

The MAX961–MAX964/MAX997/MAX999 single-supply
comparators require hysteresis to be added with external
comparators feature internal hysteresis, ultra-high-
resistors. The fixed internal hysteresis eliminates these
speed operation, and low power consumption. Their

outputs are guaranteed to pull within 0.52V of either rail
The MAX961/MAX963 include internal latches that allow
storage of comparison results. LE has a high input
impedance. If LE is low, the latch is transparent (i.e.,
the comparator operates as though the latch is not pre-
sent). The comparator’s output state is stored when LE
is pulled high. All timing constraints must be met when
using the latch function (Figure 2).
without external pull-up or pull-down circuitry. Beyond-
the-Rails™ input voltage range and low-voltage, single-
supply operation make these devices ideal for portable
equipment. These comparators all interface directly to
CMOS logic.
Timing
Most high-speed comparators oscillate in the linear
region because of noise or undesirable parasitic feed-
back. This can occur when the voltage on one input is
close to or equal to the voltage on the other input.
These devices have a small amount of internal hystere-
sis to counter parasitic effects and noise.
Input Stage Circuitry
The MAX961–MAX964/MAX997/MAX999 include inter-
nal protection circuitry that prevents damage to the pre-
cision input stage from large differential input voltages.
This protection circuitry consists of two groups of three
front-to-back diodes between IN+ and IN-, as well as
two 200Ω resistors (Figure 3). The diodes limit the dif-
ferential voltage applied to the comparator’s internal
The added hysteresis of the MAX961–MAX964/MAX997/
MAX999 creates two trip points: one for the rising input
voltage and one for the falling input voltage (Figure 1).
The difference between the trip points is the hysteresis.
When the comparator’s input voltages are equal, the
hysteresis effectively causes one comparator input
circuitry to no more than 3V , where V is the diode’s

The input circuitry allows the MAX961–MAX964/
MAX997/MAX999’s input common-mode range to
extend 100mV beyond both power-supply rails. The
output remains in the correct logic state if one or both
inputs are within the common-mode range. Taking
either input outside the common-mode range causes
the input to saturate and the propagation delay to
increase.

Circuit Layout and Bypassing

CC
One consequence of a current-driven output stage is a
linear dependence between the slew rate and the load
capacitance. A heavy capacitive load slows down the
voltage output transition.
3) On the inputs and outputs, keep lead lengths short
to avoid unwanted parasitic feedback around the
comparators. Keep inputs away from outputs. Keep
impedance between the inputs low.
Shutdown Mode
When SHDN is high, the MAX961/MAX963/MAX964/
MAX997 shut down. When shut down, the supply cur-
rent drops to 270µA per comparator, and the outputs
become high impedance. SHDN has a high input
impedance. Connect SHDN to GND for normal opera-
tion. Exit shutdown with LE low; otherwise, the output is
indeterminate.
4) Solder the device directly to the printed circuit board
rather than using a socket.
5) Refer to Figure 5 for a recommended circuit layout.
6) For slow-moving input signals, take care to prevent
parasitic feedback. A small capacitor (1000pF or
less) placed between the inputs can help eliminate
oscillations in the transition region. This capacitor
causes negligible degradation to t
source impedance is low.
