General Descript ion
These mu ltiplexers are digi tally control led 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 use d as an outp ut an d vice- ver sa. A lso the se
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 digit al contr ol si gn als of 0 to 6V. Three suppl y pins are
provided for VCC, ground, an d VEE. This enables the con-
nection of 0–5V logic signals when VCC = 5V and an anal og
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 electr ostatic damage
by diodes to VCC 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” , c onnecting one of the fo ur inputs in each sec-
tion to its common output. This enables the implementation
of a 4-channel differential multiplexer.
VHC4053: This device conta ins 6 switches whose out puts
are connect ed togeth er in pairs, thus implementin g a triple
2 channel multiplexer, or the equivalent of 3 single-pole-
double throw configur ations. Each of the A, B, o r C select
lines inde pen dently co ntr ols on e pa i r of switche s , sele cting
one of the two switches to be “on”.
