SC70, 5ns, Low-Power, Single-Supply,
Precision TTL Comparators
General Description
The MAX9010/MAX9011/MAX9013 single and MAX9012
dual, high-speed comparators operate from a single
4.5V to 5.5V power supply and feature low-current con-
sumption. They have precision differential inputs and
TTL outputs. They feature short propagation delay (5ns,
typ), low-supply current, and a wide common-mode
input range that includes ground. They are ideal for low-
power, high-speed, single-supply applications.
The comparator outputs remain stable through the linear
region when driven with slow-moving or low input-over-
drive signals, eliminating the output instability common
to other high-speed comparators. The input voltage
range extends to 200mV below ground with no output
phase reversal. The MAX9013 features complementary
outputs and both the MAX9011/MAX9013 have a latch
enable input (LE). The MAX9013 is an improved plug-in
replacement for the industry-standard MAX913 and
LT1016/LT1116, offering lower power and higher speed
when used in a single 5V supply application.
For space-critical designs, the single MAX9010 is avail-
able in the tiny 6-pin SC70 package. The single
MAX9011 is available in a space-saving 6-pin SOT23
package. The dual MAX9012 and the single MAX9013
are available in 8-pin µMAX and 8-pin SO packages. All
products in the family are guaranteed over the extended
temperature range of -40°C to +85°C.

Note 1:
All specifications are 100% tested at T
A
= +25°C; temperature limits are guaranteed by design.
Note 2:
Quiescent Power-Supply Current is slightly higher with the comparator output at V
OL
. This parameter is specified with the worst-
case condition of V
OUT
= V
OL
for the MAX9010/MAX9011 and both outputs at V
OL
for the MAX9012. For the MAX9013, which
has complementary outputs, the power-supply current is specified with either OUT = V
OL
,
OUT
= V
OH
or OUT = V
OH
,
OUT
=
V
OL
(power-supply current is equal in either case).
Note 3:
Input Offset Voltage is tested and specified with the Input Common-Mode Voltage set to either extreme of the Input Common-
Mode Voltage Range (-0.2V to (V
CC
- 1.9V)) and with the Power-Supply Voltage set to either extreme of the Power-Supply
Voltage Range (4.5V to 5.5V).

Precision TTL Comparators
Note 4:
Although Common-Mode Input Voltage Range is restricted to -0.2V
≤
V
CM
≤
(V
CC
- 1.9V), either or both inputs can go to either
absolute maximum voltage limit, i.e., from -0.3V to (V
CC
+ 0.3V), without damage. The comparator will make a correct (and fast)
logic decision provided that at least one of the two inputs is within the specified common-mode range. If both inputs are outside
the common-mode range, the comparator output state is indeterminate.
Note 5:
For the MAX9012, Input Offset Voltage is defined as the input voltage(s) required to make the OUT output voltage(s) remain
stable at 1.4V. For the MAX9013, it is defined as the average of two input offset voltages, measured by forcing first the OUT
output, then the
OUT
output to 1.4V.
Note 6:
Propagation delay for these high-speed comparators is guaranteed by design because it cannot be accurately measured
with low levels of input overdrive voltage using automatic test equipment in production. Note that for low overdrive
conditions, V
OS
is added to the overdrive.
Note 7:
Differential Propagation Delay, measured either on a single output of the MAX9012/MAX9013 (or between OUT and
OUT
outputs on the MAX9013) is defined as:
∆t
PD(±)
= |(t
PD+
) - (t
PD-
)|.
Note 8:
Latch times are guaranteed by design. Latch setup time (t
SU
) is the interval in which the input signal must be stable prior to
asserting the latch signal. The hold time (t
H
) is the interval after the latch is asserted in which the input signal must remain
stable. Latch propagation delay (t
LPD
) is the delay time for the output to respond when the latch enable pin is deasserted
(see Figure 1).
