U74LVX4053

DESCRIPTION 

The U74LVX4053 is a high speed, low-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 U74LVX4053 offer analog/digital signal selection as well as 

mixed signals wish a 4-Channel×2 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 U74LVX4053 can be used in a variety of applications, including 

in the system which has two power supplies, and in battery bachup 

circuits.
