1 VCCO Output Section Supply. 2 VCCI Input Section Supply. 3, 5, 9, 11 VEE Negative Supply Voltages. 4 VP Noninverting Analog Input. 6 VN Inverting Analog Input. 7 SDN Shutdown. Drive this pin low to shut down the device. 8 LE/HYS Latch/Hysteresis Control. Bias with resistor or current for hysteresis; drive low to latch. 10 Q Inverting Output. Q is at logic low if the analog voltage at the noninverting input, VP, is greater than the analog voltage at the inverting input, VN, if the comparator is in compare mode. 12 Q Noninverting Output. Q is at logic high if the analog voltage at the noninverting input, VP, is greater than the analog voltage at the inverting input, VN, if the comparator is in compare mode. 0 EPAD Exposed Pad. The metallic back surface of the package is electrically connected to VEE. It can be left floating because Pin 3, Pin 5, Pin 9, and Pin 11 provide adequate electrical connection. It can also be soldered to the application board if improved thermal and/or mechanical stability is desired. Rev.
