Product specification

HEF4066B

gates

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.
