Two amps is a bit much for a logic ic. Logic can drive MOSFet gates and eight small surface mount MOSFets might work as open collector buffers. Back in the day you could an array of this sort of device with a common emitter/source, but I haven't been paying attention in recent years.

These four and six channel devices might be close to what Don is talking about:

There are lots of SPI power drivers, like TPIC6595, but not 6 pins. Somebody makes a higher-current 4-channel part.

Some logic chip could drive a power buffer, like ULN2003. But 8 loads at 2 amps each is extreme. Discrete fets make more sense at these currents.

What's the load?

Wouldn’t it be just one load of 2 amps and seven open?

Thanks Buzz. looking for a direct connection to keep the timing on simple basis though.

Yes. One active of 8 at any given time. Aught to be one somewhere.
