Hi
Since nobody seems to have any suggestions regarding my other post Baffled - Please help - Quad buffer / line driver tri state circuit issue I am looking for guidance as to how I may be able to build a reliable test rig to test the 74HC125N channel by channel so that I can check my hardware.
My chips are Phillips branded and have the following markings:
74HC125N
BA427 01
UnG0624D
Currently I plan to power the chip at 3.3V between ground and VCC, tie the 3 unused "output enable inputs" to ground and use a 10K pull up on the "output enable input" for the channel under test. This will be the only component so I guess there is little point but I was going to put a 100nF decoupling capacitor as close as possible to VCC for good measure.
What should I use for the data input and how can I reliably check the data output? I do now have an oscilloscope but virtually no experience using it as yet.
I have attached the chip data sheet for reference.
Any guidance gladly received.
