The Saleae Logic Pro 16 (and probably the Logic Pro 8, but I haven't
checked) are designed for an operating input voltage range of +/-10V,
with an abs max rating of +/-25V. Saleae specifically states that it
can be directly connected to RS-232.

The Logic Pro models are more expensive than the other (amateur?)
models, but support analog input on all channels. I now use a Logic
Pro 16 for most of my simple logic analyzer requirements, but still
use an Agilent 16700 logic analyzer mainframe when I need more than 16
channels.
