M74HC4051
Single 8-channel
analog multiplexer/demultiplexer
Features
■ Low power dissipation:
– I_CC = 4 μA(max) at T_A= 25 °C
■ Logic level translation to enable 5 V logic signal
to communicate with ± 5 V analog signal
■ Low ON resistance:
70 Ω typ (V_CC - V_EE = 4.5 V)
50 Ω typ (V_CC - V_EE = 9 V)
■ Wide analog input voltage range : ± 6 V
■ Fast switching:
t_pd = 15 ns (typ) at T_A = 25 °C
■ Low crosstalk between switches
■ High ON/OFF output voltage ratio
■ Wide operating supply voltage range
(V_CC - V_EE) = 2 to 12 V
■ Low sine wave distortion:
0.02% at V_CC - V_EE = 9 V
■ High noise immunity:
V_NIH = V_NIL = 28 % V_CC (min)
■ Pin and function compatible with
74 series 4051

Description
The M74HC4051 is a single 8-channel analog
multiplexer/demultiplexer fabricated with silicon
gate C²MOS technology, pin-to-pin compatible
with the equivalent metal gate CMOS4000B
series. It contains 8 bidirectional and digitally
controlled analog switches.
A built-in level shifting is included to allow an input
range up to ± 6 V (peak) for an analog signal with
digital control signal of 0 to 6 V.
Table 1. Device summary
The V_EE supply pin is provided for analog input
signals. It has an inhibit (INH) input terminal to
disable all the switches when is at high level. For
operation as a digital multiplexer/demultiplexer,
V_EE is connected to GND.
A, B and C control inputs select one channel out
of eight. All inputs are equipped with protection
circuits against static discharge and transient
excess voltage.
