Each channel can be individually programmed to transmit data in either direction. Data is transmitted across the isolation barrier by coupling plementary pulses through high voltage 0.4p F capacitors. Receiver circuitry restores the pulses to standard logic levels. Differential signal transmission rejects isolation-mode voltage transients up to 1.6k V/µs. D2A R/T2A ISO150 avoids the problems monly 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 25m W 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.
