...unless the loads on the other end of the multiple output have low enough
impedances to cause the output conformance of the buffer amp to be exceeded.
I.e., if the multiple sinks are trying to draw more than a few mA (up to 10,
typically), then most common opamp buffers won't hold their output voltage.
If, on the other hand, those sinks all have the standard 100k input
impedance, then that really is a crappy S&H design!
