DESCRIPTION

The HEF4016B has four independent 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). Current through a switch will not cause additional VDD current provided the voltage at the terminals of the switch is maintained within the supply voltage range; VDD ≥ (VY, VZ) ≥ VSS. Inputs Y and Z are electrically equivalent terminals.

APPLICATION INFORMATION

Some examples of applications for the HEF4016B are:

• Signal gating

• Modulation

• Demodulation
