The input voltage range includes ground for single- 3 100k CD4011 supply operation and V for split supplies. A low power 1/4 supply current of 2 mA, which is independent of supply voltage, CMP04 makes this the preferred comparator for precision applications 12 requiring minimal power consumption. Maximum logic inter- face flexibility is offered by the open-collector TTL output. Figure 2a.

Electrostatic charges as high as 4000 V readily WARNING accumulate on the human body and test equipment and can discharge without detection. Although the CMP04 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are ESD SENSITIVE DEVICE recommended to avoid performance degradation or loss of functionality. 2 REV. E
