Is this chip gone or has it been renamed because it is too old? [Copy link]

 

This chip has not been found. Does anyone know what it will be called after the name is changed? If it is discontinued, what should be used to replace it?

What do you plan to use it for? DIY or making products?

There is MC1468. However, this model is old, and the newer model is MC12148.

Ok, thanks!

Replacement products on the part of the circuit, need to be purchased through formal channels, preferably the original factory agent

No, I couldn't find it on the Mouser Electronics official website. Because this is to be used on products, you need a formal channel, don't even think about Taobao or something like that.

It is no longer advisable to use such ancient fossil-level devices when making products. Various oscillation circuits are now abundant, so just use new devices to redesign them.

The key is to have a sinusoidal output

There are many signal generator chips with sine wave output now. If you want to be cheap, you can use the Wien bridge circuit. If there is an MCU in the system, you can use DAC/PWM plus active low-pass. For fixed frequency, as long as the frequency point is appropriate, you can even use a crystal oscillator with sine wave output. Don't consider such fossil-level ancient chips.
