1W multiplier

[Jester]

I have and existing circuit board that connects to another uController board with a short ribbon cable and there is only one available data signal being sent from the uC board to the remote board. I need two!

This little part looks like it would do the trick, however hand soldering an 8-X2QFN part is more of a PITA  than it's worth.

You would think there would be something like this in a more user friendly package?

I can bit bang that one available pin as required.

Any ideas or suggestions?

ICs such as that, with only a single data line and just a few outputs, may be designed for highly space-constrained environments where the routing of 5 wires from an MCU will take up too much space... so it's likely they will only be made in low area devices packages. If you could stretch to SPI or I2C, then you'll likely find many more options in larger packages, but those devices will be geared more towards functionality and more IO...

There are some QFP adapter boards (0.5mm pitch) if its just that it needs to be breadboard-able... but still requires soldering. It's not impossible, but if you've not got a nice sharp soldering iron tip or hot air... still a total PITA - not gonna argue with that!

How fast does the interface need to run? If you're going direct to another MCU, then just the TX line of a UART if available... could also bit-bang such an interface but the timing could be awkward depending on what each MCU is doing.
