SI88243ED-IS

Silicon Labs Si88x4x Quad Digital Isolators integrates Silicon Labs' proven digital isolator technology with an on-chip isolated DC/DC converter. This provides regulated output voltages of 3.3 or 5.0V (or >5V with external components) at peak output power levels of up to 2W. These devices provide up to four digital channels. The DC/DC converter has a user-adjustable frequency for minimizing emissions, a soft-start function for safety, a shut-down option and loop compensation. The ultra-low-power digital isolation channels offer substantial data-rate, propagation delay, size and reliability advantages over legacy isolation technologies. Data rates up to 100Mbps are supported, and all devices achieve propagation delays of only 23ns.
