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.
http://onsemi.com
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.)

1. Maximum Ratings are those values beyond which damage to the device
may occur.
2. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/ C From 65 C To 125 C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high–impedancecircuit. For proper operation, V and V should be constrained
