M74HC4051
Single 8-channel
analog multiplexer/demultiplexer
Features
■ Low power dissipation:
– ICC = 4 μA(max) at TA= 25 °C
■ Logic level translation to enable 5 V logic signal
to communicate with ± 5 V analog signal
■ Low ON resistance:
70 Ω typ (VCC - VEE = 4.5 V)
50 Ω typ (VCC - VEE = 9 V)
■ Wide analog input voltage range : ± 6 V
■ Fast switching:
tpd = 15 ns (typ) at TA = 25 °C
■ Low crosstalk between switches
■ High ON/OFF output voltage ratio
■ Wide operating supply voltage range
(VCC - VEE) = 2 to 12 V
■ Low sine wave distortion:
0.02% at VCC - VEE = 9 V
■ High noise immunity:
VNIH = VNIL = 28 % VCC (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 VEE 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,
VEE 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.
