The IsoLoop IL261 coupler combines the company's patented spintronic giant magnetoresistors (GMRs) with CMOS circuitry to fit in a 0.4-in., 16-pin SOIC. It contains four transmit channels and one receive channel. According to its manufacturer, its 110-Mbaud data rate makes it one of the fastest couplers on the market. Other features include a typical propagation delay of 10 ns and pulse-width distortion of 2 ns—a combination of parameters that ranks higher than that of solid-state couplers. The IsoLoop IL261 coupler additionally features a high transient immunity of 30 kV/µs and an operating-temperature range of −40°C to 85°C. IsoLoop IL261 couplers are sampling now, with production slated for the second quarter. Price is $5.46 each in 1000-unit quantities.
