8-Channel Analog Multiplexer • Dual 4-Channel Analog
Multiplexer • Triple 2-Channel Analog Multiplexer
General Description
These multiplexers are digitally controlled analog switches
implemented in advanced silicon-gate CMOS technology.
These switches have low “on” resistance and low “off” leak-
ages. 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” resistance and increases switch linearity. These
devices allow control of up to ±6V (peak) analog signals
with digital control signals of 0 to 6V. Three supply pins are
provided for V
CC
, ground, and V
EE
. This enables the con-
nection of 0–5V logic signals when V
CC
= 5V and an analog
input range of ±5V when V
EE
= 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
CC
and ground.
VHC4051: 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.
VHC4052: 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.
VHC4053: This device contains 6 switches whose outputs
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”.
