Hi,

I am working on a electronic project currently,http://www.instructables.com/id/DIY-TiX-Clock/?ALLSTEPS, am having trouble finding the IC TD62304 http://www.datasheetcatalog.org/datasheet/toshiba/3942.pdf on RS and Farnell(Element 14). Does anyone have other alternatives?

 

The TD62003 should work with TTL input voltages.
