I’m looking for a way to make the module foolproof with a part count as low as possible. Learn more – opens in a new window or tab. The PCB production and testing is done external.

This item will be posted 74ls3667 the Global Shipping Program and includes international tracking. Piggybacking a doesnt help, I guess because if the one onboard has lost its clamping ability the clamping of the new one wont show up anyway.
Had given up on the angle, all chip outputs were equally ugly looking.

He’s not concerned about the negative voltage rail. Will usually ship within 3 business days of receiving cleared payment – opens in a new window or tab.
Am struggling to get a single working pair of boards, I have about 5 CPU PCBs and 5 Video boards, every combination 74la367 crazy shit to one degree or another. Postage cost can’t be calculated. I have testing equipment for testing PCBs.
Welcome to the ECE Store. Gotta find what’s ‘injecting’ the weird ass datqsheet, what’s the output of the next IC in line like? Everything else works, you can play can over ride datasheeet right rifting with the joystick normally, sound is completely masked by the constant coinup noises tho.

Feed this signal into a window comparator to set the normal operating current range of the DUT, and set a level where current is too 74s367. Mouse over to Zoom – Click to enlarge. We supply up to 60V. Galaga are notorious on having the right voltage.
Swapping these out doesn’t solve the problem.
If so, how much current? If the faults are common then further consideration is needed.

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. Chip tested as fine, arse. Took the 54xx back out, no change. Back to home page. So I swapped the 51xx and sanity was restored. Select a valid country.

I’ve always used individual opto-isolators in DIP sockets to make replacement easy if the faults are not common.
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. The output of the s goes through one of the LS chips, on the scope the input to the buffer gate is a fairly clean squarewave pattern, the output is a pigs breakfast – am not at home so cant post a picture but if you imagine merging a saw tooth wave with the human heartbeat you get the picture, spiky, curvey and bumpy.
