74HC4051 Datasheet PDF – Multiplexer / Demultiplexer

Part Number: 74HC4051, 74HC4051N

Function: 8-Channel Analog Multiplexer/Demultiplexer

Package: DIP 16, SO 16 Pin Type

Manufacturer: Philips Semicondcutor, NXP


74HC4051 Multiplexer Demultiplexer


The 74HC4051, 74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features three digital select inputs (S0, S1 and S2), eight independent inputs/outputs (Yn), a common input/output (Z) and a digital enable input (E). When E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

1. Wide analog input voltage range: ± 5 V.

2. Low “ON” resistance :
(1) 80 W (typ.) at VCC – VEE = 4.5 V
(2) 70 W (typ.) at VCC – VEE = 6.0 V
(3)60 W (typ.) at VCC – VEE = 9.0 V

3. Logic level translation : to enable 5 V logic to communicate with ± 5 V analog signals

4. Typical “break before make” built in

5. Output capability: non-standard

6. ICC category: MSI


1. Analog multiplexing and demultiplexing

2. Digital multiplexing and demultiplexing

3. Signal gating
