INTEGRATED CIRCUITS LM193A/293/A/393/A/2903 Low power dual voltage comparator Product data Supersedes data of 2002 Jan 22 2002 Jul 12 Philips Semiconductors Product data Low power dual voltage comparator LM193A/293/A/393/A/2903 DESCRIPTION PIN CONFIGURATION The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max. for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage. 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. D, DP, and N Packages OUTPUT A 1 INVERTING INPUT A 2 NON-INVERTING INPUT A GND The LM193 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM193 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators. 8 V+ 7 OUTPUT B 3 6 INVERTING INPUT B 4 5 NON-INVERTING INPUT B A B TOP VIEW SL00079 FEATURES Figure 1.

Derate above 25 °C, at the following rates: N package at 9.3 mW/°C D package at 6.2 mW/°C DP package at 5.72 mW/°C 2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20 mA independent of the magnitude of V+. 3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than –0.3 VDC. 2002 Jul 12 3 Philips Semiconductors Product data Low power dual voltage comparator LM193A/293/A/393/A/2903 DC AND AC ELECTRICAL CHARACTERISTICS V+ = 5 VDC, LM193A: –55 °C Tamb ≤ +125 °C, unless otherwise specified.

Positive excursions of input voltage may exceed the power supply level by 17 V. 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 –0.3 VDC (VDC below the magnitude of the negative power supply, if used). 2. At output switch point, VO ≈ 1.4 VDC, RS = 0 Ω with V+ from 5 VDC to 30 VDC and over the full input common-mode range (0 VDC to V+ –1.5 VDC). 3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is V+ –1.5 V, but either or both inputs can go to 30 VDC without damage. 4. 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 change exists on the reference or input lines. 5. The response time specified is for a 100 mV input step with a 5 mV overdrive. 6. For input signals that exceed VCC, only the over-driven comparator is affected. With a 5 V supply, VIN should be limited to 25 V maximum, and a limiting resistor should be used on all inputs that might exceed the positive supply. 2002 Jul 12 5 Philips Semiconductors Product data Low power dual voltage comparator LM193A/293/A/393/A/2903 EQUIVALENT CIRCUIT V+ 700 kΩ 100 kΩ – + VC FREQUENCY CONTROL VOLTAGE INPUT 30 kΩ 5.1 kΩ 500 pF 3.0 kΩ 10 Ω LM393 – + OUTPUT 1 LM393 0.1 µF + V – /2 20 kΩ OUTPUT 2 20 kΩ 50 kΩ + V + /2 LM393 – NOTES: V+ = 30 VDC + 250 mVDC ≤ VC = 50 VDC 700H ≤ fO = 100 kHz Two–Decade High–Frequency VCO + V (12VDC) 2RS + VREF HI + VIN 10KΩ + RS LAMP – + 2RS +5 VDC 2N2222 – 360 Limit Comparator + +V REF 4 – V+ 100 kΩ 100 + 5V DC 360 + – + +V REF 3 – 100 kΩ 100 VO + 5V DC TTL-to-MOS Logic Converter 360 +V V+ + REF 2 – 200 kΩ 100 kΩ 100 + 5V 100 kΩ V+ DC 360 0.1 µF + – +V 2.0 kΩ VO 0 + REF 1 – 200 kΩ CRYSTAL 100 kΩ 100 I – 100 kHz Visible Voltage Indicator Crystal–Controlled Oscillator NOTE: Input of unused comparators should be grounded.
