The MC14067 multiplexer/demultiplexer is a digitally controlled
analog switch featuring low ON resistance and very low leakage
current. This device can be used in either digital or analog
applications.
The MC14067 is a 16–channel multiplexer/demultiplexer with an
inhibit and four binary control inputs A, B, C, and D. These control
inputs select 1–of–16 channels by turning ON the appropriate analog
switch (see MC14067 truth table.)
• Low OFF Leakage Current
• Matched Channel Resistance
• Low Quiescent Power Consumption
• Low Crosstalk Between Channels
• Wide Operating Voltage Range: 3 to 18 V
• Low Noise
• Pin for Pin Replacement for CD4067B

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid

signal which allows no margin at either peak. If voltage
transients above VDD and/or below VSS are anticipated on
the analog channels, external diodes (Dx) are recommended
as shown in Figure B. These diodes should be small signal
types able to absorb the maximum anticipated current surges
during clipping.
The absolute maximum potential difference between V
and VSS is 18.0 volts. Most parameters are specified up to
15 V which is the recommended maximum difference
between VDD and VSS.
