Quadruple bilateral switches
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 ³ (VY, VZ) ³ VSS. Inputs Y and Z are
electrically equivalent terminals.
