Triple 2-Channel Analog Multiplexer

General Description

The MM74HC4051, MM74HC4052 and MM74HC4053

multiplexers are digitally controlled analog switches imple-

mented in advanced silicon-gate CMOS technology. These

switches have low “on” resistance and low “off” leakages.

They are bidirectional switches, thus any analog input may

be used as an output and vice-versa. Also these switches

contain linearization circuitry which lowers the on resis-

tance and increases switch linearity. These devices allow

control of up to

6V (peak) analog signals with digital con-

trol signals of 0 to 6V. Three supply pins are provided for

, ground, and V

. This enables the connection of 0–

5V logic signals when V

5V and an analog input range

5V when V

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 V

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 deter-

mines which one of the eight switches is “on”, and con-

nects one of the eight inputs to the common output.

MM74HC4052: This device connects together the outputs

of 4 switches in two sets, thus achieving a pair of 4-channel

multiplexers. The binary code placed on the A, and B

select lines determine which switch in each 4 channel sec-

tion is “on”, connecting one of the four inputs in each sec-

tion to its common output. This enables the implementation

of a 4-channel differential multiplexer.

MM74HC4053: This device contains 6 switches whose out-

puts are connected together in pairs, thus implementing a

triple 2 channel multiplexer, or the equivalent of 3 single-

pole-double throw configurations. Each of the A, B, or C

select lines independently controls one pair of switches,

selecting one of the two switches to be “on”.
