The operating parameters of these productsremain stable across wide temperature ranges throughout their servicelife. For ease of design, only VDD bypass capacitors are required.Data rates up to 150 Mbps are supported, and all devices achieve worst-case propagation delays of less than 10 ns. All products are safetycertified by UL, CSA, and VDE and support withstand voltages of up to2.5 kVrms. These devices are available in an 8-pin narrow-body SOICpackage.High-speed operationDC to 150 MbpsNo start-up initialization requiredWide Operating Supply Voltage:2.70–5.5 VUltra low power (typical)5 V Operation:< 2.1 mA per channel at 1 Mbps< 6 mA per channel at 100 Mbps2.70 V Operation:< 1.8 mA per channel at 1 Mbps< 4 mA per channel at 100 MbpsHigh electromagnetic immunityUp to 2500 VRMS isolation60-year life at rated workingvoltagePrecise timing (typical)
