unisonic technologies co., ltd u74lvx4052 cmos ic www.unisonic.com.tw 1 of 11 copyright ? 2013 unisonic technologies co., ltd qw-r502-950.a dual 4-channel analog multiplexer/demultiplexer ? description the u74lvx4052 is a high speed, low-voltage drive analog multiplexer/demultiplexer using s ilicon 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 u74lvx4052 offer analog/digital signal selection as well as mixed signals wish a 4-channel2 configuration. the switchses for each channel are turned on by the control pin digital signals. although the control signal logical amplitude (v cc -gnd) is small,the device can perform large-amplitude (v cc -v ee ) signal switching. for example, if v cc =3v, gnd=0v and v ee =-3v, signals between -3v and +3v can be switched from t he 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 v cc ).as a result, for example, 5v signals can be permitted on the in puts even when the power supply voltage to the circuits is off. as a re sult of this input power protection, the u74lvx4052 can be used in a variety of applications, including in the system which has two power supplies, and in battery bachup circuits. ? features * low on resistance: r on =22 ?
