[sdiy] op amp substitutes

[anthony]

I was wondering just what parameter you look for when you want to see how 
much an op amp output can take high capacitative loads.

More specifically I was wondering if I could substitute one TL034 or one 
TL054 (or even '74's) for four LF356's.

The LF356's datasheet goes to the trouble to mention that it can handle high 
cap loads. But the '34 and '54 are FET input amps too (yeah I really don't 
care about the inputs - it's the OUTputs...)

This is in the Analog Shift Register circuit.
