ISO150AU

Product Summary

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/μs
ISO150 avoids the problems commonly associated with optocouplers. Optically isolated couplers require high current pulses and allowance must be made for LED aging. The ISO150’s Bi-CMOS circuitry operates at 25mW per channel
ISO150 is available in a 24-pin DIP package and in a 28-lead SOIC. Both are specified for operation from; 40?C to 85?C.
