MC74LVX8051
Analog Multiplexer /
Demultiplexer
High–Performance Silicon–Gate CMOS
The MC74LVX8051 utilizes silicon–gate CMOS technology to
achieve fast propagation delays, low ON resistances, and low OFF
leakage currents. This analog multiplexer/demultiplexer controls
analog voltages that may vary across the complete power supply range
(from VCC to GND).
The LVX8051 is similar in pinout to the high–speed HC4051A and
the metal–gate MC14051B. 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 pull–up resistors they are compatible with
LSTTL outputs.
This device has been designed so that the ON resistance (Ron) is
more linear over input voltage than Ron 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 (VCC – GND) = 2.0 to 6.0 V
Digital (Control) Power Supply Range (VCC – GND) = 2.0 to 6.0 V
Improved Linearity and Lower ON Resistance Than Metal–Gate
Counterparts
Low Noise
In Compliance With the Requirements of JEDEC Standard No. 7A
Chip Complexity: LVX8051 — 184 FETs or 46 Equivalent Gates
