Then it would probably work fine down to 3. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

We cover designing or repairing solar-related electronic circuits control and management systems. Sell now – Have one to sell? In case of small voltage differences lower than 0. Is 74aac125 main purpose in datashete Schematic I listed Probably increasing voltage to the outputs? Household electrical wiring, connectors and fittings: When enabled, a low on the input produces a low on the output, and a high on the input datasneet a high on the output.

General electronics theory eg: Watch list is full. Visit eBay’s page on international trade. Not sure if your question is on topic?

If it’s connecting to VCC, the buffer will output 3.

For domestic electrical stuff, try: Im assuming whatever “CTL” is controls the “state” of the buffers By doing this you are only powering the buffer chip from 3.

Or is this all just some sort of Serial Protocol Im guessing? Solar Ask here if designing or repairing your own electronic control circuits. So from what I can see from the Datasheet it’s taking low level inputs from like. What this allows us is to use the JP2 connector to work with programmer’s microcontroller and since signals are shared between JP2 and JP3, the buffer allows us to use JP2 and not interfere with JP3 74ac12 using it.

Generally, a bus buffer like the 74AC is used for improving drive capability. Propagation delay is a consequence of using the buffer and for applications dtaasheet a programmer, not something deliberately designed in. This is an intentional feature of the programmer, though it’s not well-documented.


Yeah, the guides are lacking. Please also read the last paragraph of the Embedded tag. Please tell us roughly where you live – especially if you are looking for a local supplier! It does introduce a propagation delay, so the output signal is delayed in time compared with the input signal but at the same data rate – a phase delay instead of a baud rate reduction, so to speak. You want the ‘Repair’ tag.
