Mystery Component on CD32 Joypad Schematic
« on: April 10, 2008, 06:42:12 AM »
I'm just about to order the parts required to build the below circuit, however there is one component I am not familiar with. It's the TL1 component in the circuit. I'm wondering if any of the electronics savvy members can tell me what it is?

I'm thinking I'm going to include the component in the circuit. Only thing is, I'm not sure where to find it in the electronics catalogue I use. I buy from Altronics Australia generally, although they don't always have what I need.

Edit:
Any Australians here know of a good source of electronic components? I've tried a couple of places and none seem to carry any 74LS165s.

Tried Jaycar, no joy there. I'm not sure if Dick Smith still sells those type of components. They're more an appliance/electrical store these days. Last time I was in Dick Smiths I had trouble getting caps and resistors, much less chips. I sure miss the Dick Smith and Tandy of old.

 You can use "high speed" 74xx equivalent, like 74ALS165, 74S165 or 74HCT165.

 For the "strange" component: it is a ferrite with 6 perforations, dimensions in the schematics (diameter 6mm, 10mm in length).

Ahh cool. It never really occurred to me to look at using the ALS or HC 74s. Thanks :-)

Regarding the ferrite component, am I likely to find this at a regular electronic component store? I've scoured my Altronics catalogue and cannot find anything remotely like it.

Actually, I still have lecture notes on a shift register we built with flip-flops back in digi electronics. Time to do some revision I think :-D

Thanks for the advice all. :)
