I'm looking for an analog multiplexer IC that functions like the Harris HA-2400 but at an affordable/cheap price. Does anyone know of such IC?

 

What are your criteria? There are literally thousands to choose from.

 

basically i just wanted to be able to switch audio inputs using an MPU, what sort of criteria am i looking for?

 

For starters:

1) Number of channels (x2 for stereo)
2) Frequency range (20-20kHz assuming audio)
3) Voltage range (±12V, for example)
4) Serial or parallel control of channel select
5) Package style, thru-hole DIP or SMT

 

1) Channels: >= 4
2) Freq range: audio (20-20kHz)
3) Voltage range: <= ±12V
4) Serial
5) Package style: thru-hole

Thanks.

 

4066 except for +- 12V.

 

The HA-2400 is not just a multiplexer, it has four independent op-amps, one on each channel, and then a 1 of 4 selector. Do you not need the built in amplifiers that the HA-2400 has?

If you just need an analog switch, then look at the DG441.

The built in amplifiers of the HA-2400 is a nice feature and I guess thats why it is expensive; I just need an analog switch with a built in decoder. Thanks for recommending the DG441

 

Why do you need such a high signal voltage?

I dont need a high signal voltage; I should have put VCC Voltage range <= ±12V; Signal voltages are just at line level;
What I'm looking for is an audio signal selector IC/circuit (CD/TAPE...ect) that can be selected/switched from a Microprocessor

 

A simple old cd4066 should work just fine. About $0.30 each plus shipping.

 

the 4066 is a quad bilateral switch, it has no decoder. the 4051 is a 1 of 8 multiplexer / demultiplexer that will switch line level signals wither direction with binary selection.

 

The OP wants a +- 12 volt part which the DG441 will do. The CD4066 and CD4051 will not support +-12 volts because they are single supply 15 volt(max) parts.

The OP said, less than 12 volts. And then cal airfield that he wanted line level audio in post 10.

I stand corrected, 4066 is not correct. 4051 should work.

A simple volts dropper/shifter could probably take care of that, cheaply.

 

Thank you everyone for your recommendations. The 4051 is a winner for me. I just ordered 10 PC for a total of $3.88 (shipping included!) Cant beat that.

Was that an eBay purchase or is there a US supplier with low shipping rates? Please let us know where you found those prices if not eBay.

Cheers

 

It was an ebay purchase
