U74LVX4051 Datasheet

8-Channel Analog Multiplexer/Demultiplexer
 
 
 
DESCRIPTION
 
The U74LVX4051 is a high speedlow-voltage drive analog
multiplexer/demultiplexer using silicon gate CMOS technology. In 3V
and 5V systems these can achieve high-speed operation with the
low power dissipation that is a feature of CMOS.  
The U74LVX4051 offer analog/digital signal selection as well as
mixed signals. The 4051 has an 8-Channel configuration.
The switchses for each channel are turned on by the control pin digital signals.
Although the control signal logical amplitude (VCC-GND) is
small,the device can perform large-amplitude (VCC-VEE) signal switching.
For example, if VCC=3V, GND=0V and VEE=-3V, signals between -3V and +3V
can be switched from the logical circuit using a signal 3V power supply.
All input pins are equipped with a newly developed input
protection circuit that avoids the need for a diode on the plus side
(forword side from the input to the VCC). As a result, for example, 5V
signals can be permitted on the inputs even when the power supply
voltage to the circuits is off. As a result of this input power protection,
the U74LVX4051 can be used in a variety of applications, including
in the system which has two power supplies, and in battery bachup circuits.
