HEF4066BT Switch, quad, 3 ... 15 V, SO-14

The HEF4066B has four independent bilateral analogue switches (transmission gates). Each switch has two input/output terminals (Y/Z) and an active HIGH enable input (E). When E is connected to VDD a low impedance bidirectional path between Y and Z is established (ON condition). When E is connected to VSS the switch is disabled and a high impedance between Y and Z is established (OFF condition). The HEF4066B is pin compatible with the HEF4016B but exhibits a much lower ON resistance. In addition the ON resistance is relatively constant over the full input signal range.

Pinning - E0 to E3 enable inputs - Y0 to Y3 input/output terminals - Z0 to Z3 input/output terminals

Application information - Analogue and digital switching
