February 2006 Rev. 6 1/15 LM193, LM193A, LM293, LM293A, LM393, LM393A Low Power Dual Voltage Comparators ■ Wide single-supply voltage range or dual supplies: +2V to +36V or ±1V to ±18V ■ Very low supply current (0.4mA) independent of supply voltage (1mW/comparator at +5V) ■ Low input bias current: 25nA typ. ■ Low input offset current: ±5nA typ. ■ Low input offset voltage: ±1mV typ. ■ Input common-mode voltage range includes ground ■ Low output saturation voltage: 250mV typ. (Io = 4mA) ■ Differential input voltage range equal to the supply voltage ■ TTL, DTL, ECL, MOS, CMOS compatible outputs
Description
These devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

4 Electrical Characteristics
Table 3. V CC
- At output switch point, V o ≈ 1.4V, Rs = 0 with VCC
- The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant,
independent of the state of the output, so no loading charge exists on the reference of input lines.
- The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The
+ -1.5V, but either or both inputs can go to +30V without damage.
- The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be
- Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the
0.3V (or 0.3V bellow the negative power supply, if used).

5 Package Mechanical Data
In order to meet environmental requirements, ST offers these devices in ECOPACK ® packages. These packages have a Lead-free second level interconnect. The category of second level interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com
