Using it to program non-5V targets as intended by the designer might make it destroy itself. If it’s connecting to VCC, the buffer will output 3. Seller information liaoxiyuan Have one to sell? And the data sheet for the RFM69W: Then the programmer would be completely powered by target. I’ve seen quite a few buffers like this on programmers Construction, mods and powering: So this is a schematic for an AVR Programmer seen here: Sauron The buffers tend to be designed with higher current-capability drivers than many low-power micros – stronger transistors, essentially.

Special financing available Select PayPal Credit at checkout to have the option to 74xc125 over time. Would level shifting be a concern in this situation? Subject to credit approval.
Not saying it’s safe. Electronics Design – specialist subreddits Audio construction: It’s more likely for higher current capability than the micro can provide, and to shield the micro from external electrical faults shorts, etc. Looking to run an ATMegap at 3. 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.
