TECHNICAL DATA

KK74HC4051A

Analog Multiplexer Demultiplexer

High-Performance Silicon-Gate CMOS

ORDERING INFORMATION

KK74HC4051AN Plastic

KK74HC4051ADW SOIC

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

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 (V

• Digital (Control) Power Supply Range (V

• Low Noise
