Features
■ Wide single supply voltage range or dual supplies for all devices: +2V to +36V or ±1V to ±18V ■ Very low supply current (1.1mA) independent of supply voltage (1.4mW/comparator at +5V) ■ Low input bias current: 25nA typ. ■ Low input offset current: ±5nA typ. ■ Input common-mode voltage range includes ground ■ Low output saturation voltage: 250mV typ. (I O = 4mA) ■ Differential input voltage range equal to the supply voltage ■ TTL, DTL, ECL, MOS, CMOS compatible outputs
Description
This device consists of four independent precision voltage comparators. All these comparators are 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.

1 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings
- Short-circuit from the output to VCC
- Pd is calculated with Tamb = +25°C, Tj = +150°C and
R thja = 175°C/W for TSSOP14 package.
- Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.
- Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC
with no external series resistor (internal resistor < 5Ω ), into pin to pin of device. Table 2. Operating conditions

3 Electrical characteristics
Table 3. Electrical characteristics at VCC
- At output switch point, VO ≈ 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 upper end of the common-mode voltage range is VCC + –1.5V, but either or both inputs can go to +30V without damage. 4. The response time specified is for a 100mV input step with 5mV overdrive. 5. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than –0.3V (or 0.3V below the negative power supply, if used). 6. Maximum values are guaranteed by design.
4 Package mechanical data
In order to meet environmental requirements, STMicroelectronics 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 STMicroelectronics trademark. ECOPACK specifications are available at: www.st.com
