I hope to be in correct place here for my post.
I would like understand the difference beetwen two 4053 (analog MUX) components; I have a circuit with an "HJ4053" (Texsas Instruments) and another circuit with a "CM053B" (always Texsas Instruments)

The difference is not clear to me from the datasheets. Is it possible that one of the two works with only positive voltages?

There is also a MC14053.

Back then the "40xx" series was new, many companies copied the first. But because they were fighting and could not talk to each other the parts are slightly different. (as close as they could) The intent was for the parts to be interchangeable.

The 74HC40xx are 5V parts. That is high speed and low voltage.

I have not used the HJ4053 or the CM053. I can not find much information. It may be that they all have the same pinout but have different on-resistance and off-resistance. Or they gave different part numbers for military grade parts. (different price)

Sorry I could not more find data.

I cannot find a datasheet for the part numbers you have. A normal 4053 is a CD4053 and a more powerful one is a 74HC4053.
The "HJ053" and "CM053B" are acronyms printed on the chip. I attached a micro-photo of the "CM053B".

The datasheet of generic "4053" is here:20233130113123[1].jpg
CDx4HC405x, CDx4HCT405x High-Speed CMOS Logic Analog Multiplexers and Demultiplexers datasheet (Rev. M)
It mentioned the "HJ053" but NOT the "CM053B": I suspect that this two have significative differences in power supply.
