U74LVX4051R
DESCRIPTION
The U74LVX4051R is a low-Ron 8-channel analog switch, suitable for use as an analog or digital multiplexer/demultiplexer. In 3V and 5V systems these can achieve high-speed operation with the low power dissipation that is a feature of CMOS.
The U74LVX4051R has three digital select inputs (S1 to S3), eight independent inputs/outputs (Y0 to Y7) and a mon input/output (Z). All eight switches share an enable input (E). A HIGH on E causes all switches into the high impedance OFF-state, independent of Sn.
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,...
