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 V
CC
to V
EE
).
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 (R
on
) is
more linear over input voltage than R
on
of metal–gate CMOS analog
switches.
• Fast Switching and Propagation Speeds
• Low Crosstalk Between Switches
• Diode Protection on All Inputs/Outputs
• Analog Power Supply Range (V
CC
– V
EE
) = 2.0 to 12.0 V

CC
– GND) = 2.0 to 6.0 V
• Improved Linearity and Lower ON Resistance Than Metal–Gate
Counterparts
• Low Noise
• Chip Complexity: VHC4051 — 184 FETs or 46 Equivalent Gates
VHC4052 — 168 FETs or 42 Equivalent Gates
VHC4053 — 156 FETs or 39 Equivalent Gates
