MC74LVXT8053
Analog Multiplexer /
Demultiplexer
High–Performance Silicon–Gate CMOS
The MC74LVXT8053 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 LVXT8053 is similar in pinout to the high–speed HC4053A,
and the metal–gate 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
TTL–type input thresholds. The input protection circuitry on this
device allows overvoltage tolerance on the input, allowing the device
to be used as a logic–level translator from 3.0V CMOS logic to 5.0V
CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic while
operating at the higher–voltage power supply.
The MC74LVXT8053 input structure provides protection when voltages
up to 7V are applied, regardless of the supply voltage. This allows the
MC74LVXT8053 to be used to interface 5V circuits to 3V circuits.
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.
