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

when V

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.

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”.

. This enables the connection of 0–5V logic signals

5V. All three devices also have an inhibit control

5V and an analog input range of ±5V when
