TC4051B has 8 channels configuration. TC4052B has 4 channel × 2 configuration and TC4053B has 2 channel × 3 configuration. The digital signal to the control terminal turns “ON” the corresponding switch of each channel, with large amplitude (VDD − VEE) can be switched by the control signal with small logical amplitude (VDD − VSS [ ... ]
