U74LVX4051
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.
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...
