EMULTIPLEXER
High-Performance Silicon-Gate CMOS
The IN74HC4051 utilize silicon-gate CMOS technology to
achieve fast propagation delays, low ON resistances, and low
OFF leakage currents. These analog multiplexers/demultiplexers
control analog voltages that may vary across the complete power
supply range (from V
CC
to V
EE
).
The Channel-Select inputs determine which one of the Analog
Inputs/Outputs is to be connected, by means of an analog
switch, to the Common Output/Input.When the Enable pin is
high, all analog switches are turned off.
The Channel-Select and Enable inputs are compatible with
standard CMOS outputs; with pullup resistors, they are
compatible with LS/ALSTTL outputs.
Fast Switching and Propagation Speeds
Low Crosstalk Between Switches
Diode Protection on All Inputs/Outputs
Analog Power Supply Range (V
CC
-V
EE
)=2.0 to 12.0 V
Digital (Control) Power Supply Range (V

-GND)=2.0 to 6.0 V
Low Noise

For voltage drops across the switch greater than 1.2 V (switch on), excessive V
CC
current may be
drawn;
i. e., the current out of the switch may contain both V
CC
and switch input components. The
reliability of the device will be unaffected unless the Maximum Ratings are exceeded.
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-impedance circuit. For proper operation, V
IN
and
V
OUT
should be constrained to the range indicated in the Recommended Operating Conditions..
Unused digital input pins must always be tied to an appropriate logic voltage level (e.g.,
either GND or V
CC
). Unused Analog I/O pins may be left open or terminated.
