MC74LVXT8051
Analog Multiplexer/
Demultiplexer
HighâPerformance SiliconâGate CMOS
The MC74LVXT8051 utilizes siliconâgate 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 LVXT8051 is similar in pinout to the highâspeed HC4051A
and the metalâgate MC14051B. The ChannelâSelect 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 ChannelâSelect and Enable inputs are compatible with
TTLâtype input thresholds. The input protection circuitry on this
device allows overvoltage tolerance on the input, allowing the device
to be used as a logicâlevel translator from 3.0 V CMOS logic to 5.0V
CMOS Logic or from 1.8V CMOS logic to 3.0 V CMOS Logic while
operating at the higherâvoltage power supply.
The MC74LVXT8051 input structure provides protection when
voltages up to 7.0 V are applied, regardless of the supply voltage. This
allows the MC74LVXT8051 to be used to interface 5.0 V circuits to
3.0 V circuits.
This device has been designed so that the ON resistance (Ron) is
more linear over input voltage than Ron of metalâgate CMOS analog
switches.
