Analog Multiplexers /
Demultiplexers
High–Performance Silicon–Gate CMOS
The MC74VHC4051, MC74VHC4052 and MC74VHC4053 utilize
silicon–gate CMOS technology to achieve fast propagation delays,
low ON resistances, and low OFF leakage currents. These analog
multiplexers/demultiplexers control analog voltages that may vary
across the complete power supply range (from VCC to VEE).
The VHC4051, VHC4052 and VHC4053 are identical in pinout to
the high–speed HC4051A, HC4052A and HC4053A, and the
metal–gate MC14051B, MC14052B and MC14053B. The
Channel–Select inputs determine which one of the Analog
Inputs/Outputs is to be connected, by means of an analog switch, to the
Common Output/Input. When the Enable pin is HIGH, all analog
switches are turned off.
The Channel–Select and Enable inputs are compatible with standard
CMOS outputs; with pullup resistors they are compatible with LSTTL
outputs.
These devices have been designed so that the ON resistance (Ron) is
more linear over input voltage than Ron of metal–gate CMOS analog
switches.

APPLICATIONS INFORMATION
The Channel Select and Enable control pins should be at
VCC or GND logic levels. VCC being recognized as a logic
high and GND being recognized as a logic low. In this
example:
VCC = +5V = logic high
GND = 0V = logic low
The maximum analog voltage swings are determined by
the supply voltages VCC and VEE. The positive peak analog
voltage should not exceed VCC. Similarly, the negative peak
analog voltage should not go below VEE. In this example,
the difference between VCC and VEE is ten volts. Therefore,
using the configuration of Figure 15, a maximum analog
signal of ten volts peak–to–peak can be controlled. Unused
analog inputs/outputs may be left floating (i.e., not
connected). However, tying unused analog inputs and
outputs to VCC or GND through a low value resistor helps
minimize crosstalk and feedthrough noise that may be
picked up by an unused switch.
Although used here, balanced supplies are not a
requirement. The only constraints on the power supplies are
that:
VCC – GND = 2 to 6 volts
VEE – GND = 0 to –6 volts
VCC – VEE = 2 to 12 volts
and VEE ≤ GND
WhenvoltagetransientsaboveVCCand/or below VEE are
anticipated on the analog channels, external Germanium or
Schottky diodes (Dx) are recommended as shown in Figure
16. These diodes should be able to absorb the maximum
anticipated current surges during clipping.
