The ISO150 is a two-channel, galvanically isolated data coupler capable of data rates of 80MBaud, typical. Each channel can be individually programmed to transmit data in either direction. Data is transmitted across the isolation barrier by coupling complementary pulses through high voltage 0.4pF capacitors. Receiver circuitry restores the pulses to standard logic levels. Differential signal transmission rejects isolation-mode voltage transients up to 1.6kV/s.
