•
The LM393B and LM2903B devices are the next
generation versions of the industry-standard LM393
and LM2903 comparator family. These next
generation B-version comparators feature lower offset
voltage, higher supply voltage capability, lower supply
current, lower input bias current, lower propagation
delay, and improved 2 kV ESD performance and input
ruggedness through dedicated ESD clamps. The
LM393B and LM2903B can drop-in replace the
LM293, LM393 and LM2903, for both "A" and "V"
grades.

Stresses 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 under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
Production Processing Does Not Necessarily Include Testing of All Parameters.
All voltage values, except differential voltages, are with respect to network ground.
Differential voltages are at IN+ with respect to IN–.
Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
Input current flows thorough parasitic diode to ground and turns on parasitic transistors that increases ICC and may cause output to be
incorrect. Normal operation resumes when input current is removed.

The voltage at either input should not be allowed to go negative by more than 0.3 V otherwise output may be incorrect and excessive
input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be
in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state.
Either or both inputs can go to maximum VCC level without damage.

The voltage at either input should not be allowed to go negative by more than 0.3 V otherwise output may be incorrect and excessive
input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be
in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state.
Either or both inputs can go to maximum VCC level without damage.

Full range (minimum or maximum) for LM2903 is –40°C to 125°C. All characteristics are measured with zero common-mode input
voltage, unless otherwise specified.
VCC MAX = 30 V for non-V devices and 32 V for V-suffix devices.
The voltage at either input should not be allowed to go negative by more than 0.3 V otherwise output may be incorrect and excessive
input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be
in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state.
Either or both inputs can go to maximum VCC level without damage.

7 Detailed Description
7.1 Overview
These dual comparators have the ability to operate up to absolute maximum of 36 V (38 V for the "B" version) on
the supply pin. This device has proven ubiquity and versatility across a wide range of applications. This is due to
very wide supply voltages range, low Iq and fast response of the devices.
The open-drain output allows the user to configure the output's logic high voltage (V OH) and can be used to
enable the comparator to be used in AND functionality.

Figure 7-1. Schematic (Each Comparator)
7.3 Feature Description
The comparator consists of a PNP darlington pair input, allowing the device to operate with very high gain and
fast response with minimal input bias current. The input Darlington pair creates a limit on the input common
mode voltage capability, allowing the comparator to accurately function from ground to V CC– 1.5 V input. Allow
for VCC– 2 V at cold temperature.
The output consists of an open drain NPN (pull-down or low side) transistor. The output NPN sinks current when
the negative input voltage is higher than the positive input voltage and the offset voltage. The V OL is resistive
and scales with the output current. See Figure 6-3 for VOL values with respect to the output current.
7.4 Device Functional Modes
7.4.1 Voltage Comparison
The device operates solely as a voltage comparator, comparing the differential voltage between the positive and
negative pins and outputting a logic low or high impedance (logic high with pullup) based on the input differential
polarity.

8 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification, and TI
does not warrant its accuracy or completeness. TI’s customers are responsible for determining
suitability of components for their purposes. Customers should validate and test their design
implementation to confirm system functionality.
8.1 Application Information
The device is typically used to compare a single signal to a reference or two signals against each other. Many
users take advantage of the open drain output to drive the comparison logic output to a logic voltage level to an
MCU or logic device. The wide supply range and high voltage capability makes this comaprator optimal for level
shifting to a higher or lower voltage.

8.2.2.1 Input Voltage Range
When choosing the input voltage range, the input common mode voltage range (V ICR) must be taken in to
account. If temperature operation is below 25°C the V ICR can range from 0 V to VCC– 2.0 V. This limits the input
voltage range to as high as V CC– 2.0 V and as low as 0 V. Operation outside of this range can yield incorrect
comparisons.

The following is a list of input voltage situation and their outcomes:
1. When both IN- and IN+ are both within the common-mode range:
a. If IN- is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking current
b. If IN- is lower than IN+ and the offset voltage, the output is high impedance and the output transistor is not
conducting
2. When IN- is higher than common-mode and IN+ is within common-mode, the output is low and the output
transistor is sinking current
3. When IN+ is higher than common-mode and IN- is within common-mode, the output is high impedance and
the output transistor is not conducting
4. When IN- and IN+ are both higher than common-mode, the output is low and the output transistor is sinking
current
8.2.2.2 Minimum Overdrive Voltage
Overdrive Voltage is the differential voltage produced between the positive and negative inputs of the
comparator over the offset voltage (V IO). To make an accurate comparison the Overdrive Voltage (V OD) should
be higher than the input offset voltage (V IO). Overdrive voltage can also determine the response time of the
comparator, with the response time decreasing with increasing overdrive. Figure 8-2 and Figure 8-3 show
positive and negative response times with respect to overdrive voltage.
8.2.2.3 Output and Drive Current
Output current is determined by the load/pull-up resistance and logic/pullup voltage. The output current produces
a output low voltage (V OL) from the comparator. In which V OL is proportional to the output current. Use Section
6.14 to determine VOL based on the output current.
The output current can also effect the transient response. See Section 8.2.2.4 for more information.
8.2.2.4 Response Time
Response time is a function of input over drive. See Section 8.2.3 for typical response times. The rise and falls
times can be determined by the load capacitance (CL), load/pullup resistance (RPULLUP) and equivalent collectoremitter resistance (RCE).
•
•
The rise time (τR) is approximately τR ~ RPULLUP × CL
The fall time (τF) is approximately τF ~ RCE × CL
– RCE can be determine by taking the slope of Section 6.14 in its linear region at the desired temperature, or
by dividing the VOL by Iout

9 Power Supply Recommendations
For fast response and comparison applications with noisy or AC inputs, TI recommends to use a bypass
capacitor on the supply pin to reject any variation on the supply voltage. This variation can eat into the input
common-mode range of the comparator and create an inaccurate comparison.
10 Layout
10.1 Layout Guidelines
For accurate comparator applications without hysteresis it is important maintain a stable power supply with
minimized noise and glitches. To achieve this, it is best to add a bypass capacitor between the supply voltage
and ground. This should be implemented on the positive power supply and negative supply (if available). If a
negative supply is not being used, do not put a capacitor between the IC's GND pin and system ground.
Minimize coupling between outputs and inverting inputs to prevent output oscillations. Do not run output and
inverting input traces in parallel unless there is a V CC or GND trace between output and inverting input traces to
reduce coupling. When series resistance is added to inputs, place resistor close to the device.
