The push-pull CMOS output stage allows power and space saving by eliminating the external pull-up resistor required by usual opencollector output comparators. Output 2 Thus response times remain similar to the LM339. 1 14 Output 1 2 13 Output 4 VCC + 12 V CC - Inverting Input 1 4 - + 11 Non-inverting Input 4 Non-inverting Input 1 5 + - 10 Inverting Input 4 Inverting Input 2 6 - + 9 Non-inverting Input 3 + - 8 Inverting Input 3 Non-inverting Input 2 February 2007 Rev 3 3 Output 3 7 1/11 www.st.com 11 Schematic diagram 1 TS3704 Schematic diagram Figure 1.

All voltage values, except differential voltage, are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive and negative supply voltages. 4. Guaranteed by design. 5. Pd is calculated with Tamb = +25°C, Tj = +150°C and Rthja = 80°C/W for DIP14 package Rthja = 150°C/W for SO14 package Rthja = 175°C/W for TSSOP14 package 6. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 7. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of connected pin combinations while the other pins are floating. 8. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. Table 2.
