Quadruple bilateral switches
DESCRIPTION
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.
