DESCRIPTION

The U74LVX4051 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 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.

switching.

-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

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.
