This message is a reply to 74244N for CD-7, does any online store have any in stock? -nt- posted from Tommmmy posted at September 03, 2001 at 14:57:12

Sorry for the confusion. I've posted the parts list before with the 74LS244 but the schematic program I used didn't have a symbol for a 74LS244 so I used a 74244 symbol on the schematic which is pin compatible with the LS version but has different ratings. I'd use the 74LS244 when building it.

Specifically the part in my CD7 is a DM74LS244N. You can order this online from Digikey, http://www.digikey.com/scripts/us/dksus.dll?Detail?Ref=25193&Row=98458

Another important note I've made in the past that you may have missed is that the 25 pin connector plugs onto the back side of the PCB. Everything else plugs on the front side.
