KK74HC4051A
Analog Multiplexer Demultiplexer
High-Performance Silicon-Gate CMOS
ORDERING INFORMATION
KK74HC4051AN Plastic
KK74HC4051ADW SOIC
TA = -55° to 125° C for all packages
The KK74HC4051A 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 VCC
to VEE).
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 PIN ASSIGNMENT
• Analog Power Supply Range (VCC-VEE)=2.0 to 12.0 V
• Digital (Control) Power Supply Range (VCC-GND)=2.0 to 6.0 V
• Low Noise

* For voltage drops across the switch greater than 1.2 V (switch on), excessive VCC current may be drawn;
i. e., the current out of the switch may contain both VCC 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, VIN and VOUT 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 VCC).
Unused Analog I/O pins may be left open or terminated.
