MAX9140/MAX9141/
MAX9142/MAX9144
40ns, Low-Power, 3V/5V, Rail-to-Rail
Single-Supply Comparators
General Description
Features
The MAX9140/MAX9141 are single and the MAX9142/
MAX9144 are dual/quad high-speed comparators optimized
for systems powered from a 3V or 5V supply. The MAX9141
features latch enable and device shutdown. These devices
combine high speed, low power, and rail-to-rail inputs.
Propagation delay is 40ns, while supply current is only
150μA per comparator.
The input common-mode range of the devices extends beyond
both power-supply rails. The outputs pull to within 0.3V of
either supply rail without external pullup circuitry, making these
devices ideal for interface with both CMOS and TTL logic. All
input and output pins can tolerate a continuous short-circuit
fault condition to either rail. Internal hysteresis ensures clean
output switching, even with slow-moving input signals.

either supply rail) without damage or false output inversion.
Note 4: VOS is defined as the center of the input-referred hysteresis zone. See Figure 1.
Note 5: 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 6: The polarity of IB reverses direction as VCM approaches either supply rail.
Note 7: Specified over the full common-mode voltage range (VCMR).
Note 8: Specification is for current flowing into or out of the output pin for VOUT driven to any voltage from VCC to GND while the part
is in shutdown.
Note 9: Specified between any two channels in the MAX9142/MAX9144.
Note 10: Specified as the difference between tPD+ and tPD- for any one comparator.
Note 11: Applies to the MAX9141 only for both SHDN and LE.
Note 12: Applies to the MAX9141 only. Comparator is active with LE driven high and is latched with LE driven low (VOD = 10mV). See
Figure 2.
Note 13: Applicable to the MAX9141 only. Comparator is active with the SHDN driven high and is shutdown with SHDN driven low.
Shutdown enable time is the delay when the SHDN is driven high to the time the output is valid. Shutdown disable time is the
delay when the SHDN is driven low to the time the comparator shuts down.

Single-Supply Comparators
Detailed Description
The MAX9140/MAX9141/MAX9142/MAX9144 singlesupply comparators feature internal hysteresis, high
speed, and low power. Their outputs are pulled to within
300mV of either supply rail without external pullup or
pulldown circuitry. Rail-to-rail input voltage range and lowvoltage single-supply operation make these devices ideal
for portable equipment. The devices interface directly to
CMOS and TTL logic.
Most high-speed comparators oscillate in the linear region
because of noise or undesired parasitic feedback. This
tends to occur when the voltage on one input is at or
equal to the voltage on the other input. To counter the
parasitic effects and noise, the devices have an internal
hysteresis of 1.5mV.
The hysteresis in a comparator 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. The average of the trip points is the offset
voltage. When the comparator’s input voltages are equal,
the hysteresis effectively causes one comparator input
voltage to move quickly past the other, thus taking the
input out of the region where oscillation occurs. Standard
comparators require hysteresis to be added with external
resistors. The devices’ fixed internal hysteresis eliminates
these resistors. To increase hysteresis and noise margin
even more, add positive feedback with two resistors as a
voltage divider from the output to the noninverting input.
Figure 1 illustrates the case where IN- is fixed and IN+ is
varied. If the inputs were reversed, the figure would look
the same, except the output would be inverted.
The MAX9141 includes an internal latch that allows
storage of comparison results. The LE pin has a high input
impedance. If LE is high, the latch is transparent (i.e., the
comparator operates as though the latch is not present).
The comparator’s output state is latched when LEis pulled
low (Figure 2).
Shutdown Mode (MAX9141 Only)
The MAX9141 shuts down when the SHDN pin is low. When
shut down, the supply current drops to less than 12μA, and
the three-state output becomes high impedance. The SHDN
pin has a high-input impedance. Connect SHDN to VCC for
normal operation. Exit shutdown with LE high (transparent
state); otherwise, the output will be indeterminate.

Input Stage Circuitry
The devices include internal protection circuitry that prevents
damage to the precision input stage from large differential
input voltages. This protection circuitry consists of two
back-toback diodes between IN+ and IN- as well as two
series 4.1kΩ resistors (Figure 3). The diodes limit the
differential voltage applied to the internal circuitry of the
comparators to be no more than 2VF, where VF is the
forward voltage drop of the diode (about 0.7V at +25°C).
For a large differential input voltage (exceeding 2VF), this
protection circuitry increases the input bias current at IN+
(source) and IN- (sink).
Input Current =
(IN+ - IN-) - 2VF
2 × 4.1kΩ
Input current with large differential input voltages should
not be confused with input bias current (IB). As long as the
differential input voltage is less than 2VF, this input current
is equal to IB. The output is in the correct logic state if one
or both inputs are within the common-mode range.

Figure 2. MAX9141 Timing Diagram with Latch Operator
Output Stage Circuitry
The MAX9140/MAX9141/MAX9142/MAX9144 contain a
current-driven output stage as shown in Figure 4. During
an output transition, ISOURCE or ISINK is pushed or pulled
to the output pin. The output source or sink current is high
during the transition, creating a rapid slew rate. Once the
output voltage reaches VOH or VOL, the source or sink
current decreases to a small value, capable of maintaining
the VOH or VOL static condition. This significant decrease
in current conserves power after an output transition has
occurred.
One consequence of a current-driven output stage is a
linear dependence between the slew rate and the load
capacitance. A heavy capacitive load will slow down a voltage
output transition. This can be useful in noisesensitive
applications where fast edges may cause interference.

Applications Information
Circuit Layout and Bypassing
The high-gain bandwidth of the MAX9140/MAX9141/
MAX9142/MAX9144 requires design precautions to realize the full high-speed capabilities of these comparators.
The recommended precautions are:
1) Use a PCB with a good, unbroken, low-inductance
ground plane.
2) Place a decoupling capacitor (a 0.1μF ceramic capacitor
is a good choice) as close to VCC as possible.
www.maximintegrated.com
Figure 3. Input Stage Circuitry
3) Pay close attention to the decoupling capacitor’s bandwidth,
keeping leads short.
4) On the inputs and outputs, keep lead lengths short to avoid
unwanted parasitic feedback around the comparators.
5) Solder the device directly to the PCB instead of using
a socket.
