Datasheet IN74HC4051N, IN74HC4051DW Datasheet (INTEGRAL)

Analog Multiplexer Demultiplexer

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

to VEE).

CC

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.

This device c ontains p rote ction ci rcuitr y to guard a gainst damage d ue to high st atic voltages or electr ic 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

and V

IN

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

). Unused Analog I/O pins may be left open or terminated.
