Re: [N8VEM-S100:6030] Question about the S100 FP Mini

I would use 74LS when available.

For the one-shots (74LS123) you MUST use LS version.

Thanks. Hope this helps.

For those who are building Don's Front Panel Mini I have a few questions that I hope you can help with.

I am about done with the Front Panel Mini and I have a few questions.

The Bill of Materials lists  595-5N74LS00DR from Mouser but the board socket is labeled 7400. Which IC do I use 74LS00 or 7400.
The BOM lists 595-SN74LS02DR from Mouser but board socket is labeled 7402. Which IC 74LS02 or 7402.
The BOM lists 595-SN74LS273N from Mouser but the part is listed as 74LS27 on the BOM and on the board the socket is listed as 7427.

Thanks for any help,

Harold Rothwell
