ISO7721DR

ISO7721DR is a Texas Instruments dual-channel digital isolator in an SOIC-8 package — a 1/1 channel-direction (one forward, one reverse) capacitive isolator rated at 100 Mbps with 11 ns typical propagation delay, a minimum 85 kV/µs common-mode transient immunity, 2.25 V to 5.5 V operation on both sides and a fail-safe high default output, over −55 to +125 °C. Selection advice: mind the isolation rating by package — in this narrow-body D package the isolation rating is 3,000 VRMS; the 5,000 VRMS figure quoted around this family belongs to the wide-body DW and DWV variants, so do not specify this code against a 5 kV isolation requirement. The DR code is the SOIC-8 large tape-and-reel packing. TI lists this code as Active (Production). Parameters verified against Texas Instruments documentation.
