LogicLevel Conversion for Digital Addressing Signals of 3 V to V (V DD – V SS = 3 V to V) to Switch Analog Signals to V PP (V DD – V EE = V) Matched Switch Characteristics, r ON = 5 Ω (Typical) for V DD – V EE = 15 V Very Low Quiescent Power Dissipation Under All DigitalControl Input and Supply Conditions, 02 µW (Typical) at We use the circuit above to select audio input from DVD, AUX, TUNER and MP3 PLayer Because IC 4052 contain two pair of 4 channel switch so we can use only one IC in stereo system To activate selector we must set INHpin to LOW (grounded) Then to select one of the input we use the binary code in ACTL and BCTL pin The CD4052 has two parallel fourtoone analogue switches built in, and two logiclevel inputs that determine which of the four inputs is connected to the output and the signals can go either way It's essentially a DP4T switch except you get to control it digitally with a SP4T , which it probably more commonly available, and a bit less bulky

Cd4052 audio switch

Cd4052 audio switch-The CD4052 analog multiplexers demultiplexers are digitally controlled analog switches having low "ON" impedance and very low "OFF" leakage currents Control of analog signals up to 15Vpp can be achieved by digital signal amplitudes of 3−15V For example, if VDD = 5V, VSS = 0V and VEE = −5V, analog signals from −5V to 5V can be So four relays are required to switch (the 4 pairs of audio signals) X1,Y1 X2,Y2 X3,Y3 X4,Y4 Because in the IC there are four switches that can control the four pairs above So with this IC 4 speakers are controllable by a digital CPU

Per LA County's Public Health order, beginning October 7, all persons ages 12 must be prepared to show proof of full FDA or WHO approved COVID19 vaccination (a full 14 days after final dose was administered), or a negative test taken within 72 hours of visit, prior to entry to the theme parkPersons ages 18 must also show photo ID Verification will take place when required basedSwitch is tied to either the input (when the switch is on) or to VSS (when the switch is off) This configuration eliminates the variation of the switchtransistor threshold voltage with input signal and, thus, keeps the onstate resistance low over the full operatingsignal rangeTo Switch Analog Signals to VPP (VDD – VEE = V) Matched Switch Characteristics, rON = 5 Ω (Typical) for VDD – VEE = 15 V Very Low Quiescent Power Dissipation Under All DigitalControl Input and Supply Conditions, 02 µW (Typical) at VDD – VSS = VDD – VEE = 10 V • Binary Address Decoding on Chip • 5 V, 10 V, and 15 V

3V to V (VDDVSS = 3V to V) to Switch Analog Signals to VPP (VDDVEE = V) • Matched Switch Characteristics, rON = 5Ω (Typ) for VDDVEE = 15V • Very Low Quiescent Power Dissipation Under All DigitalControl Input and Supply Conditions, 02µW (Typ) at VDDVSS = VDDVEE = 10V • Binary Address Decoding on Chip • 5V, 10V and 15V CrackJack Joined 127 #42 Audioguru said If the supply to the microcontroller is 5V then its outputs will try to go to 5V which is too high for the CD4051 that has a supply that is only 3V So the input protection diodes on the control input of the CD4051 conduct and cause currents that are too high for both ICsFor 4PDT Switch, See MCB

 So you can see the Vdd of CD4052 is 5V and the delay time is 30~60 nS, if you want to get higher frequency then you can use 74HC4052 74HC4052 page 6, VCC = 45 V, 167~139 ns/V If you insist to use cd4052 then you can increasing Vcc to get the frequency more higher shown in #3 as 10V or 15V and add a voltage divider as 1/2 for 10V or 1/3 or 15V to get a 5V outputA, B, and C, and an inhibit input Each control input selects one of a pair of channels which are connected in a single pole, double throw configuration It is a digitally controlled analog switch having low ON impedance and very low OFF leakage current Electrically, the stepper can be a CD4013 wired as a switch debouncer plus 2bit counter With 1x4 analog muxes, this gives four states in continuous rotation all off, position 1, position 2, position 3, repeat 1 CD4013 dual D flipflop 2 CD4052 analog muxes (three switches plus an unused spare) 1 SPST switch 1 resistor, debouncing
