Maybe there is a problem with the power rails – perhaps a damaged datadheet that provides power or gnd to the chips – I have had problems with my own 74ks367 in the past when I have had similar results – the chips end up “deriving” their power from the signal lines, but not enough to run reliably. There are items available. Please enter a valid ZIP Code. If so, how much current?
Dipswitches not having reliable effect proven that its not due to the s or the dip blocks themselves.
74LS367 Hex Buffer Tri-State
Either that chip is bad, the socket it’s in is bad, or something TTL-related connected to it is bad or there’s a broken track connecting that chip to something else, or a shorted track. Resume making your offerif the page does not update immediately. I’m looking for a way to make the module foolproof with a part count as low as possible.
At the very least I can use it to go through the vast array of customs I have from other boards, if I can separate datasueet duff ones from the workers I could save myself a lot of headaches.
This does reduce the drive current slightly, and the 1NB ‘s also introduce some small amount of capacitance not specified in the datasheet which will slow down fast transitions slightly.

If a high-pass transistor is used, then you risk coupling this datashset directly into Vcc, likely destroying everything. Prices are subject to change without notice. Add to watch list.
Details about such an approach should be asked in a separate question. Engineering Program is accredited by: USB will likely limit the total current available to mA. A few notes 74ls3677 this and USB:. By the way – this aint the Galaga board that has stinking hot buffer chips, I have a box of boards, trying to match up good pairs 74ps367 CPU and Vid boards datashet then address their little issues once a semi decent match is made.
Function over form I say. OT a little, it’s just like the VW beetle I’m working datqsheet, a pan with a body, and a whole lot of non original bits in the mix. Welcome to the ECE Store. Hmmm, I guess dying ICs can do all sorts of weird things, I guess if the output of the s are tied to somewhere else that’s shokttky, it’ll clean up enough to make things work.
We probably need a schematic of one of the output stages. Image not available Photos not available for this variation. Have one to sell?
Watch list is full. Delivery times may vary, especially during peak periods. The IO-Warriot56 doesn’t have output protection of its own. Once I knew which pins were input and which were output I ruled out the dipswitch theory, thats where I got sidetracked before into thinking the buffer outputs looked nasty. Powering on and off didn’t help either, it was still a squealing mess.
Have never seen a galaga board with ribbon connectors in good nick, they are always a total wreck. The board booted and reset, booted and reset.
I’ve always used individual opto-isolators eatasheet DIP sockets to make replacement easy if the faults are not common. Will usually ship within 3 business days of receiving cleared payment – opens in a new window or tab. We supply up to 60V. Select a valid datawheet.
The fact that the board seems to flip between free play, and needing coins suggests something upstream of the dips is a problem, which are two s proven goodgoing to the and then onto the bus.
