Do not connect to these pins. 2 −IN Negative Input. 3 +IN Positive Input. 4 −VS Negative Supply. 6 VOUT Output Voltage. 7 +VS Positive Supply 8 DISABLE/SELECT Power-Down/Select. The power-down function places the device into low power consumption mode. The select function of this pin shifts the crossover point (where the NPN/PNP input differential pairs transition from one to the other) closer to either the positive supply rail or the negative supply rail.
