In Fig. 104-3(a), when YIN is between reference voltages VL and VU, output VOUT goes low. If VIN ＞VL IC2 produces a low. Because IC1 outputs low, if VIN＞VU, both outputs are low and VOUT is low. If VIN<VL both IC1 and IC2 are low. Figure 104-3(b) operates the reverse of this; it produces a high when VL<VIN < VU.
