3 Description
The device consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. The LM193-MIL device is characterized for operation from −55°C to +125°C.

All characteristics are measured with zero common-mode input voltage, unless otherwise specified. (2) 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 – 2 V. 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.

8.2.2 Detailed Design Procedure
When using the device in a general comparator application, determine the following:
- Input Voltage Range
- Minimum Overdrive Voltage
- Output and Drive Current
- Response Time
8.2.2.1 Input Voltage Range
When choosing the input voltage range, the input common mode voltage range (VICR) must be taken in to account. If temperature operation is below 25°C the VICR can range from 0 V to VCC– 2.0 V. This limits the input voltage range to as high as VCC– 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 (VIO). To make an accurate comparison the Overdrive Voltage (VOD) should be higher than the input offset voltage (VIO). Overdrive voltage can also determine the response time of the comparator, with the response time decreasing with increasing overdrive. Figure 8 and Figure 9 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 will produce a output low voltage (VOL) from the comparator. In which VOL is proportional to the output current. Use Typical Characteristics to determine VOL based on the output current. The output current can also effect the transient response. See Response Time for more information.
8.2.2.4 Response Time
Response time is a function of input over drive. See Application Curves for typical response times. The rise and falls times can be determined by the load capacitance (CL), load/pullup resistance (RPULLUP) and equivalent collector-emitter 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 Typical Characteristics in its linear region at the desired temperature, or by dividing the VOL by Iout
8.2.3 Application Curves
The following curves were generated with 5 V on VCC and VLogic, RPULLUP = 5.1 kΩ, and 50 pF scope probe. Figure 8. Response Time for Various Overdrives Figure 9. Response Time for Various Overdrives
