Some manufacturers voted for 3V (because they use internal controllers with 3.3V > supplies and want to keep the circuits as simple as possible) but I'd recommend at least 5V even if this requires additional level > shifters (for some of our modules these level shifters are 30% or more of the circuit, e.g. A-160-1/2, A-161). I'd vote for a threshold level as small as possible. The highest trigger voltages I know are 12V. To my experience even retriggering due to transient overshoots does not happen with such high trigger signals (on the usual cricuits) with a threshold down to 1 Volt. Looking at the 3.3V argument I'd vote for a threshold level of 2V too. About the minimum length I vote for 5ms, because it makes software based debouncing much easier.
