How does the CD4066 Work? - Electrical Engineering Stack Exchange
Jan 3, 2017 · Is the 4066 equivalent to four independently controllable relays, where one relay switches on the pair X1,Y1?-Is this the purpose of this IC? So four relays are required to switch (the 4 pairs of audio signals) X1,Y1
Is the 4066 appropriate for power switching? - Electrical …
I'd thought of using a 4066 switch to some LED's to indicate the state of the interface for troubleshooting (TxD, RxD and PPS) and I'm wondering if the 4066 is feasible for switching power inputs. The USB module (an EM-406A) draws about …
Need some advice on how to use 4066 CMOS bilateral switch
Jul 26, 2009 · Assuming this, I have built a +/- 5v with reference to ground power supply to use on them (I have 10 4066 chips). The signal from the pickups goes +- 1.5v max. Next (and most important) question: On the 4066, to switch (the switches) on, I raise the control pin to +5v, to turn them off do I need to take the control pin to -5v or will ground work.
power supply for 4066 analog bilateral switch - All About Circuits
Mar 5, 2018 · It is recommended that power supply for the 4066 when used as an analog bilateral switch is +/- 5V. In my circuit that amplitude modulates a sine wave signal, the power supply for that circuit is +/- 8V. Will this degrade operation of the switch, and if so, in what way?
4066 Bi-Lateral switch versus Transistor to emulate a button push …
May 14, 2021 · With this the 4066 IC was ideal, single chip, low power and simple bridging switch closed the circuit and simulated pushing of the analog switch. Which appeared to work, but one issue I found was that when the IC was unpowered the circuits defaulted to a state that bridged or triggered a button push.
How to implement bilateral switch in LTSpice? e.g. cd4066b?
Jun 12, 2020 · The 4066 is already in LTS, use F2 > CDLogic select, ref: this image. E . Reactions: mggg and atferrari ...
Switching with CD4066 - All About Circuits
Mar 18, 2010 · The 4066's have too much resistance to be used with greater than line-level signals. try using 2.2k for your pull-down resistor. That will give roughly 5.6mA current max through your 1N4148 diodes.
Audio Signal Switching - "DPDT switch vs. 4066"
Nov 11, 2014 · The voltage that 4066 can switch is limited by its supply rails. If the switched signal extends outside of the supply rails, the 4066 will clip it. A relay can switch considerably higher voltages. A mechanical relay would introduce practically no noise into the signal that it's switching. The 4066 will introduce a small amount of noise.
signal inversion question (4017 + 4049 + 4066) - All About Circuits
Nov 27, 2020 · Each "switch" in the 4066 is the same as a spst switch contact. The 4017 output is controlling the state of the "contact". A high to the 4066 control pin closes the switch contact. A low opens the switch contact. If you place an inverter between the 4017 output and the 4066 control pin, you will reverse the control of the switch.
CMOS 4066 Question - Electrical Engineering Stack Exchange
Feb 28, 2014 · If one would like the output to stay at its present voltage when the 4066 is disabled, and if one is driving a high-impedance load, one may instead use a capacitor. If a capacitor is used, then while the 4066 is enabled the cap voltage will swing toward the input, and when it is disabled it will tend to stay more or less where it is (though it ...
