It does introduce a propagation delay, so the output signal 74wc125 delayed in time compared with the input signal but at the datashete data rate – a phase delay instead of a baud rate reduction, so to speak. So, this means I have both the RFM69W and the programmer hooked into the same rows on the breadboard. No generic ‘which is best’ and ‘where to buy’-type questions please.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. Just saying I’ve done it. You want the ‘Repair’ tag. No additional dafasheet charges at delivery! Yeah, the guides are lacking. Please enter a valid ZIP Code. Home audio repairs especially for vintage gear: This is an intentional feature of the programmer, though it’s not well-documented. Not saying it’s safe.


Extra rules apply to questions on vehicle electronics – please read before posting. When enabled, a low on the input produces a low on the output, and a high on the input produces a high on the output. The schematic clearly shows the CTL signal going to the output enable inputs of the part.

Quad Bus Buffers (3-state)

In terms of delays, the buffer isn’t like a memory buffer in the computing realm – it doesn’t inherently store data so that it can be transmitted more slowly. You are covered by the eBay Money Back Guarantee if you receive an item 74xc125 is not as described in the listing.

A subreddit for practical electronic engineering questions: There are items available.

Using it to program non-5V targets as intended by the designer might make it destroy itself. If set to “no power,” then you can let your target board supply VCC ostensibly 3.

I imagine the switch disconnects the 5V USB but what do the data pins output?

Datasheet «74AC125»

Datasheeh list is full. This programmer supports both a programming 5 V targets, and also b programming 3 V targets — in particular, 3 V targets that are not 5 V tolerant. What is the point of Buffers like this in Programmers? I actually use this setup in a device we’ve designed at work. Is the main purpose in the Schematic I listed Probably increasing voltage to the outputs?
