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” leakages. They are bidirectional switches,
thus any analog input may be used as an output and
vice-versa. Also these switches contain linearization cir-
cuitry 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 connection 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
determines which one of the eight switches is “ON”, and
connects 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
section is “ON”, connecting one of the four inputs in each
section to its common output. This enables the imple-
mentation of a 4-channel differential multiplexer.
VHC4053: 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”.
