An old CD player used this Toshiba device: TC17G005AF-0048. not sure what's inside the device. I need such a device -- in function at least. Maybe something like this: https://www.ti.com/lit/ds/symlink/sn74als832a.pdf

???

 

not sure what's inside the device. I need such a device

Will any device work as long as you don't know what is inside?

 

TC17G005AF-0048 is an ASIC for a very particular functionality.
The 74ALS832 is a hex 2-input driver.
Where did you get the idea that the second device could remotely replace the first?

 

The position of the TC17G005AF-0048 in the shown schematic is important: between the DF and DAC. Connected by three I2S lines. Normally, such an arrangement means some sort of "re-clocking". But that is often done using 74 logic chips:

There is a partial datasheet of "TC17G005" here:

This is an ASIC
ASICs are general purpose devices, as are FPGAs and CPLD's
They are programmed,
Its like having a ARM CPU,
its general purpose,
depending upon the programming,
Unless you have the programming, the knowledge is just about useless.

You are the one who said you needed a generic gate array. That does refer to a chip that needs programming. An asic might or might not need programming.

What you need s a replacement for the part in that schematic, and it might well be impossible to find because it is proprietary part made for the manufacturer and not available to anyone else.

I have three Asics here,
all the same package, and same silicon inside,
but with different metalisation,
performing three very different functions,
(I know cause I was involved in designing them )
The data sheet you showed was for the general silicon part of the chip,
