MC74LVXT8051
Analog Multiplexer /
Demultiplexer
High−Performance Silicon−Gate CMOS
The MC74LVXT8051 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 V_CC to GND).
The LVXT8051 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
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 3.0 V CMOS logic to 5.0V
CMOS Logic or from 1.8V CMOS logic to 3.0 V CMOS Logic while
operating at the higher−voltage 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 (R_on) is
more linear over input voltage than R_on of metal−gate CMOS analog
switches.
