Finding an IC that EasyEDA can supply for my application

Hi, I am struggling to find a suitable IC which I can replace my 16x MOSFET & 2 shift register combo with to reduce weight, size and cost. I am looking for a part which can be supplied by EasyEDA. Currently I am building with the TLC6C598 http://www.ti.com/lit/ds/symlink/tlc6c598-q1.pdf but it is not listed on the EasyEDA parts list or on the LCSC site. Would you be able to suggest a viable alternative? The application is running 16 channels to LED strips (some RGB, some White) which require 12V to power them. The IC needs to be run off 3.3/5v logic to interface with the ESP8266 microcontroller. Many thanks for your time, I would really like to be able to get another prototype built but I will need to find a suitable replacement for the TLC6C598 before I can. James

You need to do some more searching. :) I searched the web using: `8 16 channel led shift register driver ic` and found lots of possible alternative parts from Linear Technology, Maxim, NXP (Nexperia as they are now), OnSemi, ST etc., etc. Many of them already have suitable Schematic Symbols and PCB Packages in the EasyEDA library. One: LED1642GW is available from LCSC: https://lcsc.com/search?q=LED1642GW * Although several others that I looked at appear to be unavailable from LCSC stock, I did not check all of them. I'd suggest that you email Support to ask if LCSC can obtain parts for you. Note that the symbol and package for the LED1642GW are user contributions so please check them very carefully before you use them.

Thank you Andy, I really appreciate your response. I have been fighting my way through data sheets with little knowledge of what I am looking at so I am most grateful for your more practiced eye here. I'll have a look into the LED1642GW and others. I was under the impression that if I wanted EasyEDA to build my board as well as print it, that I could only use parts from the official LCSC parts list in the schematic editing tool. Is this incorrect? Am I able to assign user contributed components to my design and have them still assemble? Many thanks again, James

`I was under the impression that if I wanted EasyEDA to build my board as well as print it, that I could only use parts from the official LCSC parts list` That's true and at present it is only parts from the **Assembly LCSC Components** section and all of which are surface mount. However, please note that the assembly (PCBA) service is still being set up so you'll need to contact support to discuss your requirements. Please also not that the parts I found are probably not equivalents to your original TI parts so you'll almost certainly need to redesign the processor interface and rewrite your code.
