See test circuit and waveforms. 2. This parameter is guaranteed but not tested. 3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.

Ideally an input voltage between 0.2V and 3.6V will keep RON flat. The PI3L100 was designed to switch between various standards such as 10 Base-T, 100 Base-T, 100 VG-Any LAN, and Token Ring. Also general purpose applications such as loopback, line termination, and line clamps that might normally use mechanical relays are also ideal uses for this LAN Switch (see Figure 4). Generally speaking, this LAN Switch can be used for data rates to 200 Mbps and data signal levels from 0V to 3.6V. LAN Standards Signal Distortion Distortion of the input signal is equated to 20 LOG ΔRON/RL. So keeping RON flat as the data signal level varies is critical to low distortion. It should also be noted that increasing the data rate increases harmonic distortion which also effects the signal amplitude.
