The maximum allowed voltage swing in such a transient is .

'Peak-to-peak' amplitude (sometimes abbreviated as 'p-p') refers to the total voltage swing of a signal, which is double the peak amplitude of the signal.

Small voltage swings are not uncommon, but they are usually very mild and brief.

Within an integrated circuit a bootstrap method is used to allow internal address and clock distribution lines to have an increased voltage swing.

The result is a delay between the applied input at the base and the voltage swing at the collector.

The large voltage swings and requirement for positive and negative supplies increases power consumption of the interface and complicates power supply design.

Differential signaling with low voltage swing (1600 mV)

This can double the voltage swing at the load as compared with the same amplifier used without bridging.

(Even though current is delivered to the load, usually a large current signal into the load implies a large voltage swing across the load as well.)

If each wire carries half the signal voltage swing as in fully differential outputs then longer cable runs can be used without the loss of high frequencies.
