Alphanumeric Decoder

[aalauzier]

Is there an IC that takes 5 digit binary counter and decodes it into letters on an alphanumeric, or 14, 16 segment LED display? Thanks for the help.

Not one that's readily available. There was one that converted binary to BCD but it's obsolete.

The easy way is to use a BCD instead of a binary counter. Then you can use a BCD to LED display converter chip to display the numbers.

Is there anywhere to get a logic diagram made into an IC?

Yes. It's typically done with a field programmable gate array (FPGA), but that won't work for your need since a binary to BCD conversion is a sequential process, not a simple logic function.

An alternate is to use a programmable read-only memory (PROM) and generate a look-up table of binary to BCD values. The binary signal is used to address the PROM with each address containing the BCD equivalent of the binary address.
