Philips Semiconductors Product specification
16-channel analogue
multiplexer/demultiplexer HEF4067B
MSI
DESCRIPTION
The HEF4067B is a 16-channel analogue
multiplexer/demultiplexer with four address inputs (A0to
A3), an active LOW enable input (E), sixteen independent
inputs/outputs (Y0to Y15) and a common input/output (Z).
The device contains sixteen bidirectional analogue
switches, each with one side connected to an independent
input/output (Y0to Y15) and the other side connected to
the common input/output (Z).
With E LOW, one of the sixteen switches is selected (low
impedance ON-state) by A0to A3. All unselected switches
are in the high impedance OFF-state. With E HIGH all
switches are in the high impedance OFF-state,
independent of A0to A3.
The analogue inputs/outputs (Y0to Y15 and Z) can swing
between VDD as a positive limit and VSS as a negative
limit. VDD to VSS may not exceed 15 V.
