These MM74HC4051 multiplexers are digitally controlled analog switches implemented
in advanced silicon-gate CMOS technology. They have low “on” resistance and low “off” leakages.
They are bidirectional, thus any analog input may be used as an output and vice-versa.
Also these switches contain linearization circuitry which lowers the on resistance
and increases switch linearity.
They allow control of up to ±6V (peak) analog signals with digital control
signals of 0 to 6V.
Three supply pins are provided for VCC, ground, and VEE.
This enables the connection of 0–5V logic signals when VCC = 5V and an analog input range
of ±5V when VEE = 5V.
All three devices also have an inhibit control which when HIGH will disable all switches to
their off state. All analog inputs and outputs and digital inputs are protected from electrostatic damage by diodes
to VCC and ground.
MM74HC4051: This device connects together the outputs
of 8 switches, thus achieving an 8 channel Multiplexer.
The binary code placed on the A, B, and C select lines determines
which one of the eight switches is “on”, and connects
one of the eight inputs to the common output.

These parts came to us as part of a lot of surplus stock from a large distribution Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however in pristine condition still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
